Over the course of the last week and a half, there have been broken and remains of eggs in the nests. At first, I thought nothing of it. Chickens break eggs sometimes; it happens. Then it started happening pretty much daily. Then I knew I had an egg eater. One of the tough parts is done: finding the culprit (and she couldn't look more guilty either). My only Mottled Houdan girl, looking quite content sitting on the roost with yolk all in her beard and her crest. I have read several articles on egg eaters and she is isolated now with mustard filled eggs in a nest box. I've read somewhat mixed statements on how effective this method is, due to taste buds etc. If this fails, we'll probably move on to pinless peepers. I really would not like to cull a perfectly healthy chicken, but am not against it if all else fails. Any other tips?
