So i have a broodie who was sitting on three eggs. two BO eggs and a EE egg. Well the where scheduled to hatch today but this morning when i went to gather eggs, i looked under her cause our leghorn lays her eggs in the same box, and she was missing the green EE egg. there are 4 boxes on the bottom and on the top is like a troth. She is in the bottom right box and everyone else lays in the troth on the right side. could another chicken have stolen it or what? I want to think something got in there and took the egg but i dont get how it would have gotten out of the coop. any suggestions.
