Hi. I'm new to chickens. About 7 weeks ago I purchased 8 light brahma and 5 dark cornish straight run chicks. I will keep the brahma pullets as layers/breeders, plus one each of the brahma and cornish cockrels. I would really like to have a relatively self-perpetuating flock, so I plan on keeping the resulting resulting brahma pullets as replacement layers and the brahma x cornish chicks as broilers. So here are my questions: 1) I read in one sourse than cornish often can't breed naturally. Is this true? 2) I've read that brahmas and pure cornish grow relatively slowly. Should the crosses grow faster due to hybrid vigor? 3) Would you expect these to have decent carcass quality? 4) What color will they be? Will they be sex link? Thanks in advance.
