My sweet Banny hen two days ago went broody (not so sweet when broody) - I checked under her and she has 2 eggs. . I went and checked on her today lifted her up and she was siting on 16 eggs! The lol part is she is the only banny - ALL the rest of my chickens are LARGE Orp's and cochins with big eggs. She's barely big enought to cover them. Somehow she has threated all the girls to lay their eggs in HER box. Can i mark eggs with a sharpie marker - or will it have effect on the eggs?
