I'm glad she ate for you.![]()
Before you run out and stock pile frozen rats I would do two things: 1.) Make sure she's eating consistently for you and 2.) see if she will take a f/t rat pup. Some BPs like mice and don't want to switch and if you stock pile frozen rats and she won't take them you could find yourself with a lot of rats and nothing that will eat them.
As Redneck_Crow said, a reptile convention/show would be your best bet for now. I used to buy a months worth at a time from the pet store until I got enough BPs that I could legitimately fill a shipping box from Rodent Pro and know that they would only last 4-6 months. I think frozen rodents start to go bad after a year or so (someone can correct me on this, I only buy enough for a few months).
