We recently purchased these 20 week Barred Rock 'pullets' hatched from the same nest and while I'm no expert, I'm seeing too many features consistent with a cockerel in the larger chookie. Could I be right?
Thanks everyone for the unanimous opinion. The breeder agrees with you all and we will be swapping the cockerel for a younger pullet. This forum is so useful for newbies like me - thanks again!
