I came home yesterday afternoon and checked on my 7 month old chickens. We had 12 Ameracaunas (1 was a rooster) and 1 top-hat (Polish?) rooster. We ordered just Ameracaunas, but were given a "free exotic" chick with our order. Initially, we thought the exotic was a hen. Eventually, the hen turned into a rather dominant rooster. The Ameracauna rooster was slower to grow into his size, but they seemed to be doing ok, with only some strutting. All the hens and the Ameracauna rooster were in the house roosting when I got home. None seemed stressed. The exotic rooster was laying in the yard with just a few feathers strewn about (maybe 5 or 6). His head seemed to be picked at and he was stiff, so he must have died earlier in the day. Could the other rooster have killed him? If so, should I worry about the cannibalism and pecking? Our totally enclosed yard (enclosed with hardware cloth) seems big enough at 25 - 30 feet by 10 - 15 feet. Anyone have ideas or experience with this?
