Good question about the previous breeding history, I just shot the seller an e-mail. I'm pretty sure she was proven out at least one season, they said they didn't try last year and she is currently ready to breed. Also, on the QT, about six months ago I had zero snakes so I guess you can say my current rack has all my new additions in one big QT! My next rack will be a baby rack, I'll probably also get at least several levels of an ARS-7010 rack to put in a completely different room as a QT rack, would probably hold 3-4 snakes at a time max so I don't risk the whole collection. I'm planning on getting one more snake, probably at NARBC. Then my whole rack will be full and I won't buy another snake without a QT setup. Once the collection is established I'll have too much money in it to even try to avoid a QT. Right now I have to breed and sell some babies to pay for all the rats I'm going through LOL. I'd say right now with about 20 snakes I'm just 'dabbling' in ball python breeding, just wait until I really get ramped up!!!
