Okay, we had some egg eating and it has overnight turned into a massive problem. I have 24 chickens, some are newly bought and I don't believe are the culprits as they are rarely in the coop and I especially don't want them to learn to eat eggs. How do I nip this in the bud and get the correct culprits without getting a chicken cam for my coop? I was thinking of putting an egg into a different coop I have and putting the chickens in there one by one and see who goes for it, and culling all those that do. Does this sound like a plan?
