Help!! I have lost 3 juvenile pullets to snakes while they are sleeping in the coop. I have found them dead on the floor, with their head and neck feathers wet. Apparently the snake tried to swallow them and discovered they were too big so it had to regurgitate the chick. I totally cleaned out the coop and disinfected it and removed everything and washed down the walls two days ago and this morning found another juvenile pullet dead on the floor with a wet head and neck. Who can help me make sure this won't happen again?
