Well if you check yourself, if your not sure on what your doing you can hurt them. If you took it to a local breeder they said it was a male. Good chances are its a male. Do what you want with it. Keep it or sell it to the local pet shop or whatever. Thats up to you. If you have had it for awhile, why get rid of it? I would keep them both I would work on getting everything I need to care for them. Learn all you need to know about caring for them and breeding. Learn all you can about what is need, and how to incubate the eggs. While thats going on pick up a female or two. Grow them up when you and the snakes are ready. Then think about breeding them. From a few of your post it sounds like you have a bit more to learn, before you should think about breeding. Thats what this forum is about. Ive said this to you before this is a great place to learn everything you need to know. From care for you ball pythons to breeding and then some. Dont rush it get everything right and it will happen someday. Rush it or dont know what your doing. You will either not get any eggs or could harm your animals, or both.
