We are looking into starting a breeding line of chickens. Lets say I want to start out with chicks.. If I buy 6 female chicks... would I need to get a male chick from a different hatchery??, most likely if you order 6 female and 1 male from the same hatchery they are going to be related?? then if I hatch eggs from them and I want to keep the hens... would I then need to start two seperate line and get a different rooster from yet a different hatchery... ending up with two different lines?
