OK, so I want my eggs and eat them too....lol. What breeds do I cross to get the fast-growing Cornish Rocks? How many generations of back-breeding does it take to get the broilers? I would like to have my own for when I want meat without having to go thru a hatchery to get them. I think it is a cross between a cornish rooster and a rock hen. Does it matter the color of birds you use? And do you use standard for both the roo and hens? Thanks for any input ya'll can give me!
