I have a black Austrolorp that will sometimes leave the nesting box before her egg is out completely. I have caught her a few times hunched over and watched her finish popping the egg out onto the ground. I have even caught it in my hand a couple of times. Lately she does it almost every time and the other chickens see it or see her doing it and immediately break the egg and eat it. Luckily they have not gone after eggs in the nesting box. Any suggestions?
