My lil silkie rooster is 21 weeks old !! Just started crowing & chasing the girls around. My question is this every night for weeks he sits in the doorway of the coop (not big enough block it tho) and pecks at every girl that comes in except one. Once they get in he does a lil pecking too and everyone is trying pile up together so some of the poor girls end up pushed out the doorway or startled back out. This goes on for few mins then everyone is in & settled down ...what's up w/this?
