Thanks for the response Yes, the sickle feathers should cover the tail - and they may indeed by the time these guys finish out. Our main question/concern was the length of the primary tail feathers... they're much longer than usual, so long they're curving from the weight and length of them.
We went through a pen of Dominique cockerels today, these guys are all from the same lines and the same hatch time. They were getting a bit crowded in their pen, we meant to cull out a couple of months ago ... Anyway... we noticed that several of the cockerels had super long primary tail...
