We seemed to be plagued by snakes, usually it’s grey rat snakes getting after the eggs. I have taken to leaving golf balls in the nesting boxes, when the balls start disappearing time to watch for snakes. Had a barred rock that had gone really broody, one afternoon I found her dead in the coop. Her head & neck were all slimed up, comb was mashed down. My best guess is a snake killed her, tried to swallow her and realized she was way too big. I wonder if she was trying to protect her eggs and pecked at the snake? Not sure what kind of snake it was, but two weeks later I caught the biggest rattlesnake I have ever seen trying to get into the coop. What are others experiencing with snakes and chickens?
