New to the feeding game

[GeminiDragon]

I've been trying to research a good company to buy frozen mice/rats from and was wondering where everyone here has ordered from in the past?

Also, how do I know what types to buy for starting out with a baby boa?? Say I have one that's only a few months old, which should I buy: Pink, Large Pink, Fuzzy, or Hopper ????

I've never really seen mice up close, so I don't know how to judge whether or not they are too big to feed a baby snake.

Thanks,
