So I have 4 chickens, one Buff Orpington, One Black Sexlink, One Gold/White Sexlink, and a Rhode Island Red. The RIR, kim, (nicknamed pecker) has been very agressive pecking Nugget (G/W Sexlink) and C.C. (B Sexlink). It starred with nugget, who is the smallest, and has been pecked pretty bad and is still being pecked, and C.C. hadn't been pecked as bad, but alittle bit ago I went out and part of skin was exposed and bleeding alittle bit. And it's recent too, a few hours ago when I got home she was ok. I tried putting salt in their water in the morning, and changing it in the afternoon, and nothing so far, but then again, I just started today, and we separating Kim now. Any suggustions?
