Do you think somebody comes along in Africa and digs them out of their cozy little holes once a week to put them into a nice clean box just to feed them? Clearly, no. They ingest all kinds of things along with their meal, and since bones aren't a problem for them I doubt much is. As for the homing more than one together, she may not have meant ball pythons. Some snakes do perfectly well together, for instance my green snakes and garter snakes do just fine. However, For several months I had my three male BPs together, so I did feed them separately then. With enough hides and precautions it can be manageable, but there is still risks, although it's definitely not a life or death situation that some make it out to be. After I switched to a rack system I fed them in their tubs, and it's made no difference, except in that many times I have to let them know it's not feeding time before I grab them.
