I have one other question. How long can I leave a "pinkie" in with my snake before I can be sure she is not interested in eating it?

The first one I tried she ate within a couple hours. The other one she moved around the vivarium, so I took it out. Her diet right now is very large nightcrawlers. I put some tadpoles in for the baby snake because I haven't seen that one eat yet but she/he does alot of hunting for worms. I have had the little one now for about 3 weeks and she/he seems content.
