If the cockerel on the left of the steps, and the bottom photo, are the same, check his back. He carries his tail canted to one side, or the other.Good breast on the boy though. Lots to eat there.Their tail angle will rise as they mature. The ones that look like they have too low of tails may end up having the correct 45 degree angle. I know Walt doesn't like the fluff at the base of the tail. Wings look like they are nice & level. I like the nice rounded, forward chest on the one in the first photo.
This breed is very slow to mature, so you won't see the finished product until they are much older.
