Changing out the bedding can also help. Chickens are sensitive to scent. I had to deal with a couple of snakes in my coop earlier this year and the hens abandoned their favorite nests until I thoroughly cleaned them and changed out the bedding; I'm convinced it was because of the scent of the snakes. Good luck!Yeah, she did die in the coop. She was 11 years old, so died of old age, no predator or anything like that. Maybe I'll change things around a bit so it looks different?
