bought a new blonde silky roo last weekend, He is beating the tar out of my other silky roo!! I have only had the white silky roo since labor day, when I put him in the run the other roosters were fine with him. Now I put the new blonde in and the white roo and him wont stop fighting. I let it go until the blonde had bitten a chunk out of the whites comb and he was bloody!! I have never had aggressive silkys should I just let them fight it out?? how far should I let it go??
