I dont know how old my rooster is because I rescued him and 5 other hens. He is a golden duckwing araucana and the spurs on his legs are about 3/4 inch long. I was told that you could estimate their age by their spurs but I dont know anything about that...maybe one of you do... Anyways, he doesnt crow and he doesnt try to hook up with the ladies, either. Does anyone know why? He is the only rooster I have but where he came from, there were a bunch.
