We have 2 BLK AUS Roosters 8 wks apart in age and they are getting along just fine. One year old now and still gentle easy going. Unlike Galaxyrules, ours never shut up, crowing all day, crowing to greet you when you get out of the car, when you leave when you walk towards the coop and even in the dark of night. Not a problem for us as we enjoy the different "voices" and the neighbors are a quarter mile with their own roosters. First time with the BLK AUS and very happy with them, roos and the egg laying, six out of seven today on eggs.
