Ok, so I have three roos. Two which just won't crow. One is pretty with his little spurs and all the other no spurs but just as pretty. The breed is a toss up with those two. My third one is a NHR roo. He is about 6 months old and yet not a crow has been heard. I really was excited to hear them all. I am hoping soon they will crow! LOL Maybe I am just weird like that. At least DH says i am weird!
