Hi there. I've recently found in the last couple days that my hens are eating their eggs. I think it's just one hen. I keep finding one egg on the bottom of the coop, all the other ones are in the nesting box. They used to all lay in the boxes something changed. I've looked into certain remedies and they say to try to fill an egg with mustard I just tried that and all the chickens try to eat it. The mustard didn't deter them at all. What do I do I go out there at six in the morning there's already one broken. Please help. I looked but I can't seem to tell which chickens doing it.
