Last night I went out to check on the chickens and found one of my young pullets missing. I searched the entire coop for her and no luck but I DID find a small hole in the wire, in the corner. I put my four youngest pullets out with my laying flock last week and they've been pretty timid; staying away from the big birds. I figured they would just warm up slowly (I kept them in an adjacent pen for about 2 weeks to introduce them gradually and then put them all together on Friday. I found the little lost pullet on the wrong side of the fence (she'd clearly crawled through the hole); she's got a huge wound on the back of her neck - the skin is COMPLETELY gone. Like you can see her "chicken neck" like what you get from the store. It's a big area, maybe 2.5 inches long and 2 inches wide that's missing the skin. It's not torn, it's GONE. She seems fine and is moving around normally, eating and drinking. I pulled her out when I found her and put her in a stall by herself to heal. What could have done this? Here is the list of suspects: Feral barn cat, hunts like crazy but usually hangs out in the chicken coop without killing anything (they are too big for her; maybe she had a hard time breaking this pullets neck and gave up?) There are no punctures to indicate a cat bite, though. Dog - my dog has killed chickens in the past but it's always been a case of a chicken flying at his face and then he opens his mouth, SNAP and it's over. He's 90lbs and the size of a small pony. Unlikely that he would nibble the back of her neck and let her go. The wire where she crawled out of the pen...unlikely but maybe? Other chickens - this is my big worry. Could they have been pecking her? The skin is not torn; it's GONE. I'm afraid this might be the answer. Crows/ravens - we have a lot around here but I can't imagine they would have done this but I don't know. Something else? She was sitting in the corner where the coop was broken for about two days - I didn't think anything of it because, as I said, they had just been introduced to the flock and were shy. She may have been injured that whole time or being pecked (Oh dear), I'm not sure. Ideas? Your experience and ideas are very welcomed. As for treatment, I've sprayed the wound with Blue Kote, seperated her and she seems to be doing fine but we'll see. It's a hell of an injury, poor thing! Anything else I should do?
