We have some ducks and chicken, and 2 of them were injured today, but we're not sure by what. It happened during daylight hours, towards the end of the day. One was a buff orpington (about 3 1/2 or 4 months old)...it had one of it's wings ripped off. The other was a Cayuga duck, about 5 months old. One of it's feet had been ripped off, but the drum and thigh was still attached (the drum was in bad shape towards the bottom). The birds had no other damage or injures. Does anyone have any ideas of what could have causes this sort of damage? I worried for the other chickens and ducks we have here, but I'm not sure what to do until I can figure out what caused it.
