    We have one of our hens that started laying wrinkled eggs and they are sometimes a bit non-symetrical. Started when she resumed laying this spring. I haven't singled out the offending hen yet. We get several a week from her. They look fine inside although we usually feed these to our dog. We feed a 16% layer pellets. They get grit and oyster shell regularly. They free range in a 20 x 65 run and also have access to our entire backyard until the garden is fully planted. Any ideas?

    you can eat them the shell is just deformed, it is called a body check it is where the offending hen gets bumped around while the egg is in the oviduct it gets "healed" before it comes out.

    This is not a body check -- this is what is often referred to as "corrugated" - it's a matter of the membrane beneath the shell causing uneven/"wrinkled" shell deposit. There are a few possible causes -- Extra large egg size/often double or multi yolk eggs, Newcastle disease, excessive use of antibiotics, copper deficiency in the hen's diet, excess calcium consumption, defective shell gland and recovery from IB among them.

    it looked like it was cracked vs. the membrane being wavy. But you are right now that I look more closely it does look wavy.

    We had the exact same issue - looks like it hurts! It was not every egg she laid so I did some research ---that indicated that it could be too much calcium. I did increase their overall protein and we haven't had an issue since. I would really like to know what this means. We have one hen (Buff Orpington) who has always had a floppy comb so we assumed it was her....we have it down to her or our White Plymouth Rock.
