I don't like the idea of confining my chicken in pens, and I like the variety of colors therefore I was wondering what would happen if I had lets use Rocks (plymouths) for example : A barred Rock Rooster and a White Rock Hen, a Partridge Rock Hen. Now the chicks that they would produce would they be "purebred" would I get a mixture of Barred, White and Partridge Rocks. Could I sell them as purebreds would they breed true. The chicks if they were rebred to a rooster of there variety would get something different. I hope my question is making sense. Basically do you have to breed a White Rock Rooster to a White Rock Hen to get White Rocks or can you mix them up within the breed but still get purebreds that will breed true. Please if you don't know don't assume or speculate I would prefer an answer from somebody who has experience and has tried possibly this breeding technique.
