Haha, I think pork and fish are right, but it needs to be crossed over. My opinion is a female should be at least 3 years old. She should be at least 6ft and 18lbs. Males can breed as early as 1.5 years old...and the size doesn't matter. As long as they are interested...it's game. Males won't try unless they are ready. Also, from what I've heard from some successful boa breeders, the younger the males are the more "active" and "successful" they will be. Hormones at their best!!

Red tails of any kind are becoming more and more popular all the time for many reasons. The market is exanding and in that it makes it harder and harder to sell baby boas.
Says who? How can something become more popular for many reasons and go lower in value? The market seems, to me anyways, to be growing WITH the demand for them. Now, they will never reach the popularity of the Ball Python; however, against all popular belief, they are much harder to breed than BPs...and they don't breed every year. Females will go two or three years in a row, but then not breed for 4 or 5 years straight. There is no schedule with this either.
