Black Cochin Roo Pure Blood With Silver Leakage (Help me out)

[huzaifa415]

Hey everyone hope everyone is chirping with the sun. I’ve a quick question. I have all black Cochins pure solid at my barn but this one male showed some black leakage on his shoulders and neck. Can anyone confirms why this happens? My other birds are true solids even the chicks that are coming up are all black.

Thank you.

I know you said that he is pure, but how are you so sure?

Cochins have yellow skin, I believe I see white skin on him.

Black Cochins don’t have yellow details. The reason why I’ve said that he’s pure is because he is the only one like him from his gene. All other siblings are solid blacks and the chicks I’m getting are black too without any leakage
