I have (had) a Buff Orpington hen sitting on 12 eggs for 4 or 5 days until yesterday. Yesterday about dark I went to check on things in the hen house and the Buff hen was still in the nest box with her head sticking out but she was dead. My first thought was to pick her up and see if the eggs could be saved and put in the incubator. All 12 eggs were gone without a trace. No cracked eggs, shells or any mess of any kind. I knew snakes would sometimes eat eggs from under a setting hen but has anybody had a snake kill the hen first and then eat the eggs?
