I have some young pheasants, all hatched early/mid 2009. There are 2 Red Golden males and 5 females. I also have a Chinese Ringneck male and 3 females. They are all in a large pen now, and they all get along well. When should I separate them, I'm assuming before breeding season, and can the 2 male RG's stay in the same pen with RG 5 females? This is my first time having pheasants, and I've read that during breeding season, males of other species will kill or try to kill one another?
