Is my new BP underweight?

At 161g and 204g They have already outgrown adult mice (unless you're talking about the jumbo retired breeders that are usually around 40g).

If you have some rat pups you may want to try switching them to rats. As your snakes grow (and they will grow quickly once they are fed regularly), you'll be able to increase the size of the rat rather than feed multiple mice, which keeps things a bit easier. They may not switch to rats, but most likely they will so you may want to try it.

Hmmm, okay but the fact is that I bought 50 frozen adult mice recently and they got to go first. I could try to feed them two adult mice a week and see how they do?
