Not sure if he will have anything but try al6517, he is in OK. I know he has some very good Whites, but rarely has any for sale.Several months ago I was able to purchase 5 standard white cornsh chicks out of which I kept 1 rooster and 1 hen. Over the past 2 months I have attempted to hatch a total of 21 eggs with poor results. The eggs are fertile but few live to hatch and all but 3 have died as chicks. I have good facilities and knowledge going back over 70 years so the only thing I can think is inbreding. So do you know of any breeder in the Oklahoma, Texas, Arkansas area where I could find new blood? Feel free to reply by e-mail to [email protected]. Thank you and I will appreciate any help. David F.

I would be very interested in some of these. Could you email me a price
GENETICS 101
Find some good looking dark cornish that have reasonable fecundity to out cross with. The whites could be dominant white or recessive white. My guess is recessive white, You will find out after the first cross. I would not back cross to the white but do a sibling cross then pick the best white birds from the sibling cross. Hatch plenty of the eggs from the sibling cross- eat the offspring you do not want and breed the best.
If the white is recessive white then the F1 ( first generation) will be a non-white variety. If you do a non-white sibling (F1) cross, then some of the offspring (1 in 4) will be recessive white. Some of the non-white will be carriers (carry one recessive white allele) and some will not carry the recessive white allele. If you decide to use some of the nonwhite birds you can test cross them to find out if they are a carrier. Cross them with a recessive white bird and half the offspring will be white; the other half will be nonwhite and carriers.
If the white is dominant white then every F1 chick will be white (assuming the bird is purebred for dominant white). The dominant white sibling cross will produce mostly white birds (3/4).
You can always back cross to the dark cornish to enhance egg laying and fecundity once you establish the white color in the offspring.
Most people do not like out crossing but if you can not hatch eggs from the birds you have then eventually you will not have any birds at all. Out crossing will insure the genes from the birds will be found in future offspring.
The male in my avatar has cornish blood in his breeding. He is an offspring from cornish cross experiments.

Question Tim. I have no personal experience with dominant white, but was thinking that the F1's out of a dark / dominant white cross would likely come out looking like jubilee's. No ?
