Is that normal? They are almost 14 weeks old and have been together from day 1. I noticed a couple of the black aust. pullets picking fights with him and then one of the sex links (can't remember which) did. At one point he let out a pretty high pitched bock. Our coop is not big enough at 4 x 6 (we are building a new one) but the run is plenty big at 10 x 24.
