Ball Python Breeding.?

It's going to be tough. Normally it takes about three years to get them to breeding size, but it all depends on feeding. Some people say 1500 grams is the minimum, others say 1200. I've bred them with no problems at 1200. I have heard of people breeding females at 900 to 1000 grams, but I prefer to wait until they are at least 1200 to 1300.
