Hatching Process and When to Help


Hatching your own eggs is a wonderful experience. Caring for the eggs, making sure the temperature is just right, ensuring there is enough humidity, and then going through the nerve wracking experience of watching the chicks’ struggle to escape the shell can be very rewarding. After all of your hard work, of course you will be nervous the little ones hatch successfully. Then you see one that seems to be in trouble. Your first instinct may be to help it, and that is fine, but you should know a few things first.

As it incubates, the embryo is encased by a membrane consisting of blood vessels. These vessels provide oxygen that enters the egg through the shell to the embryo. Several days before hatching, this network of vessels begins to break down and the embryo lacks sufficient oxygen. The egg will have slowly dried out during incubation, forming an air sack. This sack is pierced by the chick in order to get oxygen. Since there is not a lot of air in the sack, the chick will continue to peck until it ‘pips’ a tiny protrusion on the shell which allows for a greater flow of oxygen. After pipping, the chick will rest for 12 to 24 hours.

Once the chick has rested, it starts to make its way out of the egg. It starts at the pip before turning slightly and pecking again. The chick will continue this pattern around the egg until it forms a ‘lid’ which it can push open and wiggle out the rest of the way. During this process, the chick will take several breaks until it is finished about 1 to 3 hours later.

These rest periods are where most nervous soon-to-be bird parents think they are needed the most. After seeing and hearing movement only to have them go quiet and still can be stressful. Knowing when and when not to help a chick hatch is important.

When you help could mean life or death for the chick. If you help before the network of blood veins has completely broken down, you can cause the chick to bleed to death. Following are three scenarios and our recommendations for each.

  • The chick forms a hole where it pipped and does not start rotating within the shell. In this situation you must be careful as not everything went as it should. You can try to help, but stop and try several hours later if you see blood forming where you have broken the shell.

    In the following video, we did not see blood until the 'lid' had been taken off. Make sure to stop and try again several hours later whenever you see blood.


  • If the duckling has started turning and breaking the shell, then runs into a problem and stops turning, you can normally help them without a problem. The key is they have started turning in the shell which means the blood vessels under the shell have shut down and you can help them without fear of excessive bleeding. Gently pull the head out from under the wing and allow the chick to escape the rest of the egg on its own.

    The following video shows a variety of eggs where the 'lid' has not been developed and the chick has not turned, but we were able to help them because there was no blood.


  • If the chick has gone completely around and formed a ‘lid’ only to get stuck, you can definitely help them out by removing the cap.

Many believe that helping during hatch will make the chick weak. This is not necessarily true. You could have a perfectly healthy and fit chick, but due to less than ideal incubation conditions, it may not be able to hatch on its own. On the flip side, it is possible to get a weaker chick when helping a less than healthy chick to hatch. As author and waterfowl expert Holderread says, hatching is like a “fitness test” for the chicks.

Broody Ducks



Any experienced waterfowl owner has seen the signs of their females going broody. To new owners, however, it can be alarming. We regularly receive frantic phone calls saying that their females have started behaving strangely and that they do not know what to do.

Broodiness is basically a biological clock that tells a female bird that it is time to sit on her eggs full time. When she lays eggs, she is not broody as she does not sit continuously on the eggs. She merely lays her eggs in the nest and then leaves. Once she has a full next of eggs, she will start sitting on the eggs to hatch them. Only in extreme instances will a female become broody without eggs in the nest. During this time she leaves her nest once a day to eat, drink, and do her business. As it is her instinct to protect her eggs, she will become territorial and grumpy. This will continue until the eggs hatch.

Most birds that become broody take care of themselves while on the nest, only leaving once or twice a day to eat and bathe. As such, they are more susceptible to predators, mites, ants, and other bugs and pests. In extreme cases of those that continue to sit on eggs that will not hatch they run the risk of malnutrition, dehydration, and even death.

If you think your bird will go broody, it is important to encourage her to nest in a safe place. This can be done by providing nesting boxes in advance. Waterfowl have a tendency of choosing a spot for their nest and sticking to it even if the nest is moved. (We had a customer call us once at her wits end. Her goose had built a nest in the middle of a high traffic walkway and was plugging up a pipe. We told her to move the nest since she did not want to destroy it, but when she did the goose rebuilt the nest in the exact same place as before!) Chris and Mike Ashton suggest in ‘The Domestic Duck’ to leave the bird alone while she is sitting and to separate her from any males. To help with exercise, Dave Holderread in ‘Storey’s Guide to Raising Ducks’ suggests placing food and water just out of reach in order to entice her to leave the nest in order to take care of her needs. We suggest switching from a layer feed to a grower feed while she is broody. In the situation that a bird goes broody, but there is no possible way for the eggs to hatch (no males in the flock), it is possible to slip fertile eggs under her or even ducklings/goslings and trick her into thinking the eggs have hatched.

There are some instances in which you do not want your bird to remain broody such as when they go broody without eggs or you rely on her for egg production. Once they start sitting, they stop laying. The best way we find to stop brooding is to take away any eggs and destroy the nest. To discourage her from attempting to make another nest, make sure there are no materials available to her to make a nest. In large-scale turkey farms they have small pens in the laying buildings that have cement or wire floors in which they put their broody hens. After they appear to have lost their broody instinct and no longer want to sit, which can take about 3-4 days, they are returned to the rest of the flock.

We find there are some breeds that are broodier than others. Sebastapol geese are the worst of the bunch on our farm, followed by the African and Buff. On the duck side, the Cayuga seem to be the broodiest followed by the Rouen. On the opposite end, we do not really know who is less broody out of our geese, but our Runner are the least likely ducks to be broody.

A bird going broody is perfectly natural and some breeds can be more broody than others. There are steps you can take to help them through it or to stop it. Hopefully these guides will help you with your broody birds.

Improving Mobility in Older Geese


A customer contacted us about how she improved the mobility of her older goose, Oliver, with Cosequin.

“Hello to all,
 

I am sharing this in the hope that it may help another goose. I have a goose named Oliver that I rescued 12 years ago. He was full grown so I don't know his real age. About 6 years ago he started to walk less and less and began just staying stationary in the yard until being put in the barn at night. He got to the point that he would barely walk and had to be picked up and carried most of the time. He would get stuck in the bedding in his barn with his feet behind him just shoveling deeper holes.

I have a wonderful bird vet in Dr. Gary Riggs. Several years ago we exhausted every avenue to get Oliver mobile again. He had Adequan injections. He was on Gabapentin and Tramadol. He even had little Dr. Scholls gel insoles glued to his feet for part of the Summer. Nothing helped him. Dr. Riggs described his feet as "gnarly". His toes are not smooth and straight as they should be and look as they may have been broken or infected at one time.

So here is the thing. About six months [ago] I put the dogs on Cosequin. There are 3 different kinds and I actually bought all three. I contacted Dr. Riggs to see if it would be ok to try on Oliver. I started Oliver on the green label bottle simply because that is the first one I bought. [The pills are] shaped like a little dog bone. It breaks in half easily. I wrap each piece in a little ball of bread and pop it down his throat. In two weeks I "thought" I saw an improvement. Now six months later I see him doing things I haven't seen him do in years. Walking....not as much as the girls but he will get up and walk a bit and graze. I have actually looked out the kitchen window and done a double take in that he was in the pond - by himself. I used to have to carry him to get him to go for a swim. He gets up and comes to the barn at night when he sees me getting water buckets ready. He can hop up in the barn with a wing flap but no longer has to be picked up.

It is the only thing he is on at this point. I have no doubt it has made a major improvement in his mobility.

I hope this helps someone else.
Linda, Reebok, Oliver and Piper”

Linda’s story reminds us that sometimes solutions to your birds’ problems can come from obscure places. If you find that your older birds have issues walking, you can try this and see if there is any improvement. From brief searches (thank you Google!), we found that Cosequin is an over-the-counter supplement for older dogs and cats that help with joint pain and Boswellia is considered an anti-inflammatory.

We do not know if this actually works or not, however, as we are not a certified vet. If you do try this, please let us know the results! If you have found an excellent cure for other waterfowl problems, please write us with your story!

What Causes Runts?


The word ‘runt’ has a lot of negative connotation to it. Runts are thought of as weak and sickly. I’m here to tell you that this is not true! The official Google definition of a runt is “an animal that is smaller than average”. A runt is just a smaller version of the same breed. That doesn’t mean it is sick or weak, just small.

What causes this? Our veterinarian’s theory is that it has to do with the flora in the gut. Everyone has bacteria in their stomach, both good and bad. The good bacteria colonizes in the stomach and helps with digestion. Runts, however, do not seem to have as much good bacteria or it has the wrong kind of bacteria colonizing in its gut. This means that it doesn’t digest its food as well and therefore does not grow as fast as its siblings.

There is a way to fix this. By providing the correct probiotics, runts are capable of catching up in growth with the rest of the flock. You can find probiotic supplement packs at your local feed store or Amazon. The probiotics help to develop the good bacteria in the bird’s gut that will help with digestion and facilitate growth. You can mix this in the communal feed as the extra probiotics may benefit your other birds, too.

Other potential causes include hatching from small eggs, viral infection, genetics, coccidiosis, and bacterial infection during incubation. While these are valid causes, our veterinarian believes they cause far fewer runts than improper bacteria in the gut.

For further information, Andy Schneider, the Chicken Whisperer, has an article in his Chicken Whisperer Magazine that goes further into probiotics for poultry. While this article is about chickens, the same applies to ducks and geese.

The main question is what this means for you. If you are a commercial producer, we suggest culling the runts if only because their growth rate will be off of your expected processing date. For example, Pekin are ready for processing at 7 weeks, but your runt may not catch up until about week 12.

The following picture is from one of our customers, a Hutterite colony in Montana in 2014. They and other colonies order Pekin ducklings by the thousands and you can clearly see in the photo that there were several ducklings that were not growing as fast as the others. They were 4 weeks and 4 days of age for the picture. When it came time for processing at 12 weeks, however, they could not tell which had been the runts!

If your main concern is egg production, a runt’s egg production start will probably be delayed. If the runt is treated, however, and catches up in growth, they should be on time to start laying with the rest of the flock.

Both the meat and eggs are still good to eat. Remember, a runt is simply smaller.

Whether your birds are pets or not, make sure you keep them all fed, watered, and warm. It will take time for them to catch up in growth, but it will be worth it in the end.

Six Steps to Keep Ducks From Eating Their Eggs

Originally posted by John Metzer on Sat, Jan 08, 2011 @ 10:27 AM 

Some poultry develop a habit of eating freshly laid eggs. We have never seen it in geese but have with ducks. It can be prevented if you follow these steps, with the most important first.


1)  Have an adequate number of well bedded nest boxes. It is highly unlikely a duck will purposely break and eat an egg. Normally they acquire the taste when an egg is accidentally broken and they find they like the taste. So make sure you have enough nests (a minimum of one nest for every four females), your birds are not overcrowded (at least five square feet per bird) and each nest has at least two inches of wood shavings, sawdust, straw or hay in the bottom. It is important there is a 3-4” front on the nest so the bedding stays in the nest. We will discuss nest construction for ducks and geese in a future blog.  We have found the larger, clumsier ducks, such as Pekins, accidentally break and then eat more of their eggs than the lighter breeds.




2)  Pick up any broken eggs quickly and do not toss cracked or broken eggs back to your ducks.

3)  Make sure your ducks are getting a well balanced layer feed that has at least 3% calcium. And remember, by mixing chicken scratch with a balanced layer feed, you are making an unbalanced layer feed. The scratch adds carbohydrates but little protein and few minerals. If you are having an egg eating problem, buy some oyster shell at your local feed store and allow them to eat as much of that as they want. Just put it in a feeder and place it in a dry spot. They may eat more than they need but not enough to harm themselves.


4)  Remove the offending ducks. Watch your birds and see which are doing the breaking and eating. Any incriminating yolk on their bills?
5)  Give the birds other things to play with and eat instead of eggs. Put in chunks of vegetables: cabbage, lettuce, carrots, beets, potatoes, etc.
6)  The last alternative is using fake eggs. Some recommend putting golf balls in the nests. Ducks are not brilliant but I think they are smart enough to quickly learn they cannot eat a golf ball, then ignore it and continue eating eggs.
Besides losing good eggs, there are also health concerns for your birds if they continually eat raw eggs. An essential vitamin is biotin and eggs contain avidin, which binds and prevents the use of biotin. Cooking deactivates the avidin. But if your birds continually eat raw eggs, they may develop a biotin deficiency.




Some people have said to put hot pepper in an egg and the birds will learn to not eat broken eggs due to the pain from the peppers. The problem with this theory, however, is that peppers cause no discomfort to birds! They even put hot pepper in bird seed to prevent squirrels from eating it! In my research I did find there is a compound, methyl anthranilate, that birds detest. It is a naturally occurring compound that is found in concord grape skins and burns the pain receptors in birds just like hot peppers do us. It is used in all sorts of bird repellents but it is not sold in smaller, retail quantities. I wonder? Is there enough methyl anthranilate in grape juice to train ducks to not eat their eggs?




I ran an experiment by putting duck feed in two troughs. In one trough I poured water on the feed at one end of the trough and Welch's grape juice on the feed at the other end. On another feeder, I poured water on half and Grape Kool-Aid on the other. The result? All was equally eaten. If there was any methyl anthranilate in either product, there wasn't enough to bother the ducks! Of course, hungry ducks will eat most anything. It is like putting two kinds of feed in front of a hungry Black Lab (our dog). Everything will be eaten – taste does not enter into the equation!
So until someone can find something with adequate amounts of methyl anthranilate in it to put in “training” eggs, you will need to follow the six steps listed above to prevent your ducks from eating their eggs.

Are My Ducklings' Leg Problems Due to a Niacin Deficiency?

Originally posted by John Metzer on Wed, Dec 29, 2010 @ 03:22 PM 

Niacin is a critical vitamin required for the correct development of ducklings and goslings.  In fact, waterfowl have a higher requirement for niacin (also called nicotinic acid) than chickens.  Niacin is formed from the amino acid tryptophan and waterfowl do not synthesize niacin well from tryptophan.

What do the birds look like if there is a niacin deficiency?   If there is a lack of niacin in their feed, initially some birds are reluctant to move about.    Eventually their hocks swell and their legs develop a bowed shape.  It becomes very difficult for them to move about and they do not gain weight or thrive.  In young birds you will see problems within several days if they do not have adequate niacin.  If they remain on a low niacin diet, death may occur within two to three weeks as it is just too painful for the birds to move to eat and drink.




A series of pictures from the book,  Nutrition and Management of Ducks, with permission of the authors, showing a normal duckling (A) and ducklings (B,C,D) that were fed Niacin deficient diets.

How can this happen?  If you are not using a balanced chick starter designed for broiler chicks or game birds, you may have problems.  If you are using a chick starter developed exclusively for laying chickens, it probably does not have enough niacin.  Do not make their diet exclusively whole grains, like Chicken Scratch.  On very rare occasions, the lack of niacin could be from a mistake at the feed mill.

So how much niacin do waterfowl require?  It should be at least 55 parts per million (ppm).  This is the same as 55mg per kilogram of feed or 55mg per 2.2 pounds of feed.  Oftentimes this is not on the label but if you contact the manufacturer of the feed, they should tell you the minimum guaranteed level in the feed.  You can go to our website for a complete list of waterfowl nutrient requirements.

A bottle of Niacin tablets, 500 mgs per tablet.

How can I supplement niacin?  Niacin can be easily purchased at a nutrition or drug store.  Typically the pills contain 500 mgs of niacin per tablet.  Assuming a duck is eating about .35 lbs per day (this is how much a Pekin is eating at about 3 -4 weeks of age) , they need 10 milligrams (mgs) of niacin a day.  So, theoretically, one pill has enough niacin for 50 ducks.  But if you are grinding up a pill and spreading it over pelleted feed, much of it will sift to the bottom and not be consumed.  Add a little water to the feed and it will “stick” to the pellets.

An alternative is to add it to their drinking water (assuming they have no swimming water).  If they drink 100% of the water you give them, you only need to add one 500 mg tablet to every 8 gallons of water.  But we both know that does not happen.  If you think they are wasting half their water, then add one 500 mg tablet to only four gallons of water.    For your own calculations,  go to the table on our website on daily feed and water consumption of ducklings.

Are there alternatives to pure Niacin?  If you are concerned with the possibility that other vitamins may be missing, too, you can purchase Vitamin B liquid supplements.  The GNC product I found had 20 mg of niacin per dropper full.  This is enough for two ducks that are 3-4 weeks old.  This might be the best way to administer niacin if your birds are exhibiting leg problems.  By administering the niacin to each bird,  you will know they are getting the required niacin.

A feed ingredient that is rich in niacin is dried brewers yeast.  There is about 5mg niacin per 15 grams (one tablespoon) of human grade brewers yeast.  Livestock grade brewers yeast is not as concentrated.  There is only about 1.5 grams niacin for each tablespoon of livestock grade brewers yeast.

If you are not sure if your problem is due to inadequate niacin, give them some sort of additional niacin as soon as possible.  You will not harm them if you give them too much niacin.  And if they quickly recover, you know you found the problem.

What if only a few of my birds have leg problems?  Variability within a flock is normal.  Each bird varies on how well it forms  niacin from tryptophan, either due to genetics or the different microflora  in their gut.  It would not be unusual to have a single flock of birds, with some exhibiting a niacin deficiency and others walking perfectly normally - but all eating the same feed. 

Glory, a duck that was rescued by Majestic Waterfowl Sanctuary,  arrived with leg problems due to a niacin deficient diet.

How long does it take for recovery?  Except for the extreme cases such as the picture above, improvement is normally seen within several days and there can be complete recovery.  But this requires adequate niacin within 24 hours of the first sign of a problem.
