Egg Eating - Possible Causes and Ways to Break This Bad Habit in Backyard Chickens


The last thing you want is for your chickens to start eating their own eggs. That kind of defeats the purpose of raising chickens. Egg eating by your chickens is a bad habit that gets harder to break the longer you let it go on. Many say that culling the offender(s) is the only way to stop it but I offer that there are a few less drastic solutions.

It generally starts by accident. An egg gets stepped on or otherwise breaks, one curious hen pecks at it and thinks - hmm this tastes good. She will then start breaking eggs as they are laid, and soon other hens will follow her lead and you'll have a whole flock laying eggs and proceeding to eat them. Your first clue might be a lack of, or reduction in the number of eggs you collect, although there are other reasons why production slows down. Other than catching an offender red-handed with yolk dripping off her beak, your best clue will be a wet mess in the nests, but no sign of an egg. The chickens will generally eat the egg, shell and all.

Basically, you want to keep the eggs from breaking in the first place, but I have some other tips for heading off egg eating before it starts - and then for 'curing' an egg eater after the fact. 

There are several things that can cause egg eating to start:

Weak-Shelled Eggs

Even a good commercial layer feed doesn't always provide enough calcium for really strong shells. If your shells are weak, a hen can step on, and inadvertently break it. Providing free-choice oyster shell or crushed eggshell can help with that. As long as you crush the eggshells into 1/4" or smaller pieces, the chickens won't associate the shells with eggs, so don't worry about feeding crushed eggshell leading to egg eating. I have been doing it for years and not had once incidence of egg eating. Ever.

And in fact, keep reading and you'll find out that feeding eggs TO your chickens can actually help prevent egg eating as well!

Not Enough Bedding in the Nesting Boxes

There should be at least 2" of soft bedding (straw, pine shavings, shredded paper, etc) in the nesting boxes to prevent eggs from breaking on the hard floor. A sheet of rubber shelf liner or an old yoga mat cut to size on the bottom of the box can also help prevent broken eggs.

I have tried both straw and shavings, but prefer straw for the nesting boxes. I have found it holds its shape better and often using shavings the chickens will make a 'bowl' in it right down to the nesting box floor and the egg will be sitting on the bare floor. I also developed an innovative new bedding product called HerBedding which is curled beech shavings with dried herbs mixed in that really holds its shape very well. And it smells good!

Not Enough Nesting Boxes

As a rule of thumb, you should provide one nesting box for every 4-5 hens, although they still will want to use the same nest...at the same time. But it can cut down on scuffles and broken eggs to provide enough boxes. You also don't want your nesting boxes to be much larger than 12-14" square. Just enough room for one hen, but not enough that two might be tempted to squeeze in there - that can lead to broken eggs as well.




 
High Visibility Nesting Boxes

Out of sight, out of mind. Believe it or not, hanging curtains across the front of your nesting boxes can deter egg eating. The curtains not only shield the eggs from open view, they make the boxes darker. If passing hens can't see the eggs as well they aren't as tempted to investigate.

Broody Hens

Broody hens can contribute to broken eggs as they fight to hold their ground and not give up a nest. Yet another good reason to break broodies if you aren't hatching eggs. 

Leaving Eggs in the Nesting Boxes After They are Laid

Eggs should be collected as quickly as possible to avoid having them sitting in the nesting boxes creating a temptation. Replace the eggs with golf balls, plastic Easter eggs, ping pong balls, wood or ceramic eggs so they will start to find that when they peck at 'eggs' they don't break and tasty yummy inside after all.


In extreme cases, or if you aren't home to collect the eggs, the nesting boxes can be replaced with the roll-away type of nest box where the floor is slanted and the eggs literally roll out into a collection tray as soon as they are laid.

Not Enough Protein

Ironically, feeding your chickens eggs can actually get them to stop eating their eggs. A protein deficiency can often be what is making them crave the egg and start eating them in the first place, so add some cooked scrambled eggs to their diet and see if that puts a stop to it. 

Other causes of egg eating may be boredom which can be 'cured' by providing outdoor roosts or logs for your hens to stand on, piles of dirt, leaves or weeds to rummage through, a hanging treat feeder or even a mirror in the coop or run.


Urban Chicken Legend: Something often mentioned on the internet to stop egg eating is to blow out some eggs and fill them with mustard and/or hot sauce. The theory is that hens will learn pretty fast that eggs don't taste good. However, it's been proven that hens taste buds aren't designed to taste or feel 'hot' or 'spicy', so don't bother.

However, the hot sauce or mustard trick can be used to deter rodents or snakes from eating the eggs, if that's a problem in your coop.

With a little persistence, it is possible to break a hen of egg eating. Culling should only be considered as a last resort.

Have you ever had any experience with egg eaters in your flock ? How did you handle the problem? I would love to hear!

  2. Great post one of the biggest issues I have with sawdust being used as bedding is the dust! It can create respiratory issues. I have found over the years that Bermuda or Timothy hay/grass make outstanding bedding. It's clean!

  3. I've had a couple of egg eaters and successfully broke them all. I'm not sure why it got started, but I put plastic easter eggs and golf balls in all the nestboxes and just let them peck to their hearts' content.

  4. I currently have a chicken who is laying thin shelled eggs. They do break in the nest boxes quite often. For the most part, my chickens don't bother with the broken egg unless I throw it down on the ground for them. I also take all the thin shelled eggs back to the coop and throw in their run. They make quick work of the raw eggs and shells, but I don't have any trouble with them getting in the nest boxes and eating the eggs. Lots of times I find eggs here and there not touched either. This has been going on the say way for quite a few years now. Hopefully I don't come upon a chicken who particularly likes eggs more than this.

  5. We always fed the egg shells back to our hens to help with their mineral levels. We seldom had egg-eaters because we did this and also gave them a mineral supplement. Be sure, however, to break the shells up very well so they don't know they are eggs' shells, see? If you feed them recognizable egg shells, it teaches them to eat eggs. Does this make sense. I just love chickens. I'm enjoying your blog.

  8. We never had an egg eater, but we always checked for eggs early and often. We also did break up the egg shells with a hand blender and fed that back to the hens. We also fed them eggs often, from the breakfast table in left over scrambled eggs, french toast etc.

  9. Good timing on this blog post! I've been dealing with egg eaters and now it seems everyone thinks it's a good idea! :-/ Done quite a few of these already, might have to try the filling eggs with mustard and hot sauce! I am guessing it is a learned behavior, I have some younger pullets I need to add to my flock but am weary of adding them till I get these girls stopped!
