I have two bantam Black Cochin roosters, 7 months old, and one, the one who was most aggressive, is turning gray. As you can see in the picture, he also has white tufts by his ears. (If their ears are where one would expect ears to be) I don't know if he is sick, his behavior is normal, other than he used to be quite bossy, and now he is a pleasant member of the flock.
