I am growing out my chicks. Problems I'm having is, in the hatcher I had a board up to keep different groups separate. They managed to get over and they were all combined. I had a Roo with a white wing feather in with my pullets but moved them into the coop with different roo and waited 4 weeks before collecting eggs. The ones that hatched from the all black hens I am able to discern at 9 weeks as they are mostly black. A lot of the cockerels have way too much copper on chest but a few pullets have a white wing feather or 2. Will these eventually disappear or are they pet quality only?
