I have a beautiful little silkie who went broodie three weeks ago. I checked on her eggs and could see one had pipped. The next morning I let all the chickens out and got to her pen opened it up and she jumped off her nest to eat drink poo..... and I saw that she had crushed 2 eggs. Every egg that started to pip or hatch she has crushed. I scooped up both eggs and rushed in side, one had blood every where so obviously she had broken lots of blood vessels and the other was just badly squashed. I gently pealed back some of the shell and put both eggs in the incubator. Sadly only one survived. That night I took the rest of her eggs and put two 3 day old chicks under her to see how she would go with chicks. She is fine and babies are going great so I gave her a few more. She is a good mum but I can't understand how she could squash the eggs hatching..........dopey chicken!!
