Hi,I am new to the forum. I have been crossing purebred LF Dark Cornish(show stock, not from McMurrays) with the Cornish Roaster hens from McMurrays. I have my first chicks on the ground. I was surprised to see the Dark Cornish coloration coming through on a few of the birds. Most are white with a few spots of dark feathering. Very good bone and heavy bodies. I have more pictures of the darker chicks- they are older. The smaller chick drinking is a pure Dark Cornish. mom is on the right. The other big/fat hen will probably never lay eggs. I limit fed them from 4 weeks up to 16 weeks. Then slowly increased the feed to allow for maturity. Just like you would a Broiler Breeder. The Roosters upon maturity died. They just are not meant to be breeders, so I went with the Dark Cornish Roo below. "BamBam" with his ladies in waiting - Dark Cornish hens: Maid Marion and Guinevere.BamBam at 10 months. I just love the Dark Cornish hen feathers. I hope your Meaty Bird project turns out well. I will update my post when the white brids mature a little more.
