I raise Cubalayas, which are wheaten. I started out with a wheaten cockerel, 2 wheaten hens , and a silver wheaten hen. I know from looking at many pictures, that the silver wheaten hen is indeed silver wheaten. Plus, when she is crossed with a regular wheaten, 100% of the babies are gold wheaten, 2 years in a row, using 2 different roosters. My silver hen has 2 faults, first, she has green eyes, and, second, she has blue legs. Keep all that in the back of your head. I have been working on some grade breeding projects with my Cubalayas, crossing them with several other breeds, then breeding back to pure over many generations. My first cross was to barred rock hens, this gives of course a black sex-link hen, and a barred with red/gold cock. The Cubalaya cocks used were either pure bb redwheaten, or gold wheaten, not sure which, either way, the F1 is the same in looks, not sure about genes.... I kept the 2 best black cross hens, and, crossed them back to another pure bb red wheaten rooster. Using the chicken color calculator, it seems that half the chicks would be wheaten, and half extended black. That is exactly what I got on hatch day, half yellow chicks, half black. No surprise there. However, as the chicks have matured, there are some big surprises!! All the wheaten hens from this cross are SILVER WHEATEN WITH GREEN EYES AND BLUE LEGS!!! The cockerel from this cross is a regular bb red wheaten, with red eyes and white legs. Even stranger, the black chicks ended up 2 cockerels, and 2 pullets..the pullets are both rusty black, and 1 cockerel is rusty black. However, the 2nd black cockerel is turning out to be sort sort of birchen, or brassy back,( maybe he will be salmon faverolles color?) he is black with a silver neck, and gold-yellow back and wings...I CANNOT figure out HOW I can possibly get these results!!!!! Can anyone explain this to me? Where are the silver wheaten hens coming from? Shouldn't they be extended black bb red wheaten hens? And, where is the weird birchen/brassy back looking guy coming from!! I keep trying the chicken calculator, but can't get these results..What do I not understand? Thanks for any help!!!
