We lost our first chicken last night, so I am trying to figure out what did it and how to prevent it. This is my first year raising chickens, so I am very new to this. The attack happened around 10:30 - 11 at night, right before I was going to close the door to the coop for the night. There were a lot of the down feathers in the coop and no chickens, so I gathered up as many as I could and noticed I was missing one. I haven't given up hope on her, but I am also realistic in thinking she isn't coming back. I think it's a fox, but I did hear coyotes that same night. I figured there would be more of a mess if it was a coyote though. Any thoughts on if it was a fox, and if so what to do to stop it? For now I'll just make sure I lock them up a bit sooner.
