I have a cock that looks like this


although his head has lost alot more of the grey feathers since these photos and is almost completely black.
I was wondering what is going to happen next...
Will he have a complete molt and his adult colours come out or will it be a slow process? Or is he going to just be a dull coloured bird?
Also, how long will/does this process take and do you think he could be ready for breeding in about 2 months time when our season starts.
I was really hoping to have a clutch this season.
