This chick was bought as a pullet from MPC. It is as big and healthy as his/her hatch mates, eats well and is not picked on and is very bright and active. Wherever white feathers should be is just grey down or bald skin. The black feathers are coming in fairly well. The other 8 chicks of various other breeds are fully feathered. Is this just a slow maturing bird or do you think there is a genetic problem with the white feather growth.... This pick was 2 weeks ago at around 7-8 weeks of age any thoughts?
