Anyone that breeds should be able to have the means to care for all offspring until they are sold, correctly. This will be my first year with hatchlings, so I guess I can properly answer your post in a few months :)
My selling outlets are online and my friend's pet store. I plan on selling/keeping the snakes in proper tubs with everything set up, and they will be for sale with such setups. Pet store selling does not have to be all evil and incorrect.
