As long as your ball goes to a good home, then I don't see any problems with it. I also do not think that selling a snake and selling a dog is the same thing. Dogs become attached to their owner. Snakes don't care who their owner is as long as their enclosures are clean, and they are fed and watered. If you want to sell your ball and buy others to breed then do that. Just make sure that you do your research and are ready for the responsibility of breeding and raising clutches. They may not sell as easily as you would think.
Good luck with whatever you decide.
