Over the years I've tried the lot! Most successful in terms of looking like a supermarket chicken but tasting much better were the ross/cobb/hubbard bought in eggs and grown as broilers. I did try to keep a couple of hubbards on for breeding but they eventually lost a lot of feathering and looked awful.
I've tried Bresse de Galouise twice now, the first lot more successful in terms of coming to any decent weight before 20 weeks. This second batch of eggs bought last autumn have grown differently and I suspect have been crossed with something else as the spare cockerels at 18 weeks were about 3 to 31/2 lbs. Not really enough to get excited about is it, but and it is a big but, they were not fed growers ad lib just mixed grain and they were trying to grow on at the worst time of year - winter. The taste and tenderness was exceptional and I did manage to get three meals out of one - so not all bad.
I've kept the heaviest boy with two of the heaviest girls and we'll see how they fare this summer.
