The fact that that white one has so much comb and wattle compared to your others at this point and the fact that it's so bold points to roo even more. Pullets are usually much more shy and prone to running away but usually settle down and get more friendly as they grow older. Roos do just the opposite. Not afraid and very bold and then become stand offish unless you do something to the pullets he gets concerned about and then watch out becuase he will get angry with you... chase you and let you know he wants you away from his girls.lol!
