robyn, it's not mine, it's of one of my buddies. She bought it by occasion, there is no infomation about its pedigree. As well there are not brothers/sisters of this bird.
She tried to breed il last year, but the cock was an unexperienced one and the eggs were infertile. Certainly, she'll try to breed this hen more.
But still, looking at this hen, I have the idea that it's of Blackfaced mutation. Maybe, it's this rare case that the mutation occured exactly in this bird. To my mind, it's worth trying to check that. I want to offer to this buddy to breed this hen with 2 different cocks and then to mate the children from different nests. It's possible also to try to breed her with her son, but it's a closer inbreeding. Generally, I'm against such inbreeding, but this case looks so special.
What do you think? Have you ever seen such birds? Is it worth trying to use the close inbreeding in this case?
