I think you may be right. But, i guess you'll never be 100% certain until he lives his life to the fullest. It seems like a "he said she said" game...some breeders won't breed them so young, some will. I don't see what the negative effects would be on breeding a juvy...but the way to find out for sure is through experience. Will breeding a young male result in "burn out" in later years? will it have negative or positive or no side effects?
