I have a 19 week old rooster who has been crowing for a long time. I let him and the hens out to free range. I went out to check on everybody and heard a bark coming from the hen house where I have 2 broody silkies. The rooster does not roost in the hen house but is free to go in and out when I have the run open for everybody to free range. When I went in the hen house he was standing in front of my silkies barking. I mean serious barking, like a dogs bark, not a sneeze or a cough. I scooted him out of the hen house and out the run and he stood there and barked several more times. I am sure the bark means something but I haven't a clue what it is. Any suggestions?
