this might be a stupid question but here we go anyways!! i got 5 buff bramha's about 3 weeks ago. four of these buff bramhas look like the chick on the left, feathers almost blonde/light brown. The chick on the right has a different color pattern than her sisters. The question is could this be a rooster or maybe not a buff color patter and is a different bramha all together. thanks for any and all help.
