So, two nights ago I heard disturbance and some urgent clucking in my chicken coop. I went out to see if it's a fox or a stray dog, and saw nothing in the area. All chickens appeared fine. After searching around the yard and seeing the chickens settle down I went inside. In the morning, I found my favorite Polish/Black Brahma pullet dead on the chicken coop floor with no visible signs of injury. I am so upset, she was just about to begin laying and was so gorgeous. My children were devastated, too. Could it have been a snake? Can snakes climb up a roost?
