Okay, I'm still a newbie at this chicken stuff so bear with me. Now that I know what kind of chickens I have and that I definitely have 5 hens and 4 Roosters. Hubby says I may keep just one Rooster when they are grown (they are only about 75 days old right now). {named the biggest on Chester, so hubby can't change his mind on letting me keep one} anyhow, is there a certain age when I should separate the Roosters away from the hens, before I get rid of three of the four? Will it matter if I keep the one Rooster with the hens even if I don't want them to brood but want the eggs?
