I have 5 hens, a barred rock, 3 RIRs and 1 Black Australorp. My Australorp is much bigger than the other girls and they are all almost 6 months. Just about a week ago, she/he gets up and crows early in the morning.. and sporadically throughout the day. It sounded awful at first, so I was convinced she was still a she.. but she seems to be getting better at it!? These are my first chickens, and I've already got a complaint from the neighbors.. not formally, but their little girl came over to play and said that her "mommy and daddy said they could hear a chicken crowing from their bed". She didn't make that up on her own!!! Here are my pics.. what do you think? Thanks!
