To me an egg eater is a chicken that purposely opens an egg to eat it. If an egg is already broken many will eat it, that's just taking advantage of an opportunity. To me that is not a problem. I've had one egg eater in my life, though I've had several that will clean up a broken egg. Usually they eat the egg and not the shell, but some will eat shells.Would you say egg eating has to do with overcrowding, or a problem with their diet -- or are some breeds more likely to go that way?
