Not that I know of, because they are basically coating the inside of the egg with calcium in their reproductive tract. And they probably wouldn't have run for that other one.Is it possible for a hen to lay a shell with no egg stuff?
Hopefully they stop soon and that it is just the initial excitement. My hens will eat an already broken egg, and a couple will go after the green one since it is easy to crack, but other than that they aren't super interested.They are on a 20% all flock right now. They rarely get treats - except for soldier fly larvae a couple of times a week - and only a couple of tbs per bird.
Oh, you can also blow an eggshell and put dish soap or mustard inside. That would probably work since it isn't an ingrained behavior right now. This makes me sound a bit evil, but it is pretty fun to watch their reactions when they try to eat it.
