Hi! I have a Cuckoo Marans that was my "free rare" from a hatchery order. I'm sure since he's from a hatchery, instead of a breeder, his coloring my not be perfect. But I'm wondering why he has a gold sheen to his black and whiteness? Is that what is referred to as 'color leaking'? It's really difficult to capture in pictures, but is seen well with the eye. I hope you can see what I'm talking about, though.
