I am new to chickens and Guineas. I have 2 Hens, 1 rooster and 6 Guineas(3male,3 female) I have had them 3 weeks now. Most of the guinea are now missing feathers on their backs & The Rooster lost so much he is almost bleeding. I caught a male guinea and the rooster fighting twice now. The Rooster is a very impressive Aracana or something like that. this all started happening in the last week. They will be free ranged but are not yet. I bought the guinea's as adults so they need 6 weeks of pen time or like homing pigeons they will try to get home. what should I do?
