I have two bucks for breeding.. They are both from two different lines. Here is a pic of the one i do like ... But I am not to sure ... He is very stocky. big head and wide butt. He is suppose to be a american chinchilla rabbit. He is only 5 months old now i have just started using him to breed because he was showing readiness over the other one that is 6 months old. But they sure dont look the same body type. Now this buck for the first time show intersted in breeding and did four times in a row ... the other buck that is 6 months old ... Only did one time breeding and couldnt anymore... I didnt take him out of the cage . But i took to pic of him. He thought i was bring him another female. He seems to like his girls... But being only 5 months ,it dose concern me a little. .. Is his bones a bit big for his age.
