This is Dooley, He comes from a very large Cuckoo Marans roo and a Wyandotte hen (I think). My assumption about the Wyandotte hen is because of his comb, but I'm not 100% certain because we have other brown egg layers too and he was hatched out of a brown egg. Our other brown egg layers are Delawares and Dark Cornish, his comb looks like Wyandotte to me though.
Anyway, he has VERY long legs that seem disproportionate to his body size. He may fill out, he's only 15 weeks old right now, but I was wondering if there could be some type of game chicken in his DNA. The hen and roo are both hatchery stock, so I guess anything is possible. Any ideas from looking at him?
