This is the second time I've found blood on the side of the feeder or waterer. From the way it looks, it appears that a chicken with a bloody head? comb? ate from the feeder and left splotches on the side. All the hens and the rooster look fine - I can see no sign of injury (although I can't get very close to these). There's a little rooster on that side who "has words" with a bigger rooster on the other side of the chicken wire fence. It might be that big roo hurt little roo and that's the cause of the blood. It's a significant amount of blood, though, and I would have thought I'd see some sort of wound. I'm more worried that it might be some sort of disease, although I can't imagine what. Any ideas? Thanks!!!
