Second time finding one of my chicks in the middle of the coop with a neck wound, skin stripped off of head. The second one had all the neck except the bone eaten away and a small wound under one wing. The first time I thought a racoon or fox had bitten it through the wire and the other chicks had pecked at it. This time I'm not so sure. All the chicks are fully feathered except for the two that were killed. Their developement had slowed way down and they still didn't have all their feathers (well, one had been slow from the start, I think they were both roosters.) They are in a coop with three bantams, two hens (one with four tiny chicks) and a rooster, that my FIL brought home a couple weeks ago.
