If you give away roo's as pets, don't give one roo with only one hen because he will overmate the one hen. A single roo as a pet if in-house is ok -- but remember that chickens have flock mentality so 2 roo's together may work depending on how they get along as hatchmates. A single roo indoors without another chicken or humans around all day might be too lonely. I don't buy chicks or hatch eggs -- I only get sexed pullets because I hate going through finding homes for cockerels that will more than likely wind up on someone's dinner plate. Amber Waves Silkies sells DNA-sexed Silkie pullet chicks (not cheap but the sex is guaranteed) and they give away free the Silkie cockerels. Cockerels/Cocks are great flock protectors but unfortunately most backyard flocks don't need more than one or two males so the extra boys get re-homed or eaten.
