OK so I have been pretty sure we have an egg eater in our little flock of 4 for the past two weeks. I go out an hour or two after hearing one of my white legghorn's egg songs and there is no egg. A few days ago we found one broken shell at the other end of the run far from the nesting boxes but thought it might be from one of the two pullets that are due to start laying any day now. Yesterday I put a plastic easter egg in the nesting box to help convince the new pullets to use the box (there is a lot of discourse in the coop over nesting boxes but I'll save that for another discussion) and when I looked late morning today, because one of the pullets was in the coop all upset, I noticed the green plastic egg gone- completely gone not in the coop or in the run. We keep the coop closed at night but the lid to the nesting boxes is unsecured. We've got a terrible rat problem right now but never see them during the day. At least one opossums has been around the house (probably feeding on the abundance of rats) also. Who would steal a plastic egg?
