I have 2 silkie roosters and a small flock of hens. the roosters have been fighting a lot recently both the roosters are very tame and they and nice to people. whats the best way to stop the fighting without selling one or killing one because Im very attached to them both they are good family pets. neither of the has been been hurt past a few feathers being pulled but i dont want this to get worse. the are both about a year old and they are brothers so they've lived together their entire life.
