Chicks? That's odd. Who did you purchase her from? I would definitely try to get her onto rats as soon as possible. Maybe get a couple of f/t chicks and try scenting the rats (just rub it up against the chick). I don't know about the nutritional facts as far as feeding chicks to ball pythons goes but it just seems to make much more sense to feed rodents.

Good luck man! You're gonna need it!
