I just got 6 Barred rocks a week ago but now that their feathers are coming in one of them looks different than the others. It is all black still with no white or grey and its beak is smaller and darker. The place had several other breeds so im thinking this was labeled as a Barred rock on mistake. What other breed could it be if it turns out to me all or mostly black with no white speckles? (Its the one in my profile pic, second up from the bottom on the right.)
