I live in the city, and have a fenced in backyard. I've never had predator trouble, except a hawk in day time. I have a secure coop, but sometimes I don't close the back chicken door until later at night (lesson learned)! Last night, I heard a terrible squawking. Took my dog with me as I ran to the coop. My chickens were flying everywhere trying to escape. My dog chased something but she didn't get it. All chickens were fine except my poor EE only has one tail feather left I've never seen raccoons, and I don't think it would have trouble killing them quickly. I was thinking possum, but then I read cats will eat chickens?! Has anyone had this experience? Any ideas about what it was? Thanks!!
