You know, Azygous, I am running out of compassion for some of my girls too. This is supposed to be fun and relaxing, and feather picking and egg eating are behaviors which interfere with those good feelings. I have a hen who is some kind of sex link who was sold to me as a Buff Orp who is an egg eater, and I will think she is finally on the straight and narrow...but not. Yesterday late in the day she came flying out of the coop with an egg and membrane flopping from her beak. She is unrepentant, and I am getting ready to learn to process her.
