I'm new to this forum and need some advice.

I have had a ball python for about 7 years now. I used to get mice one at a time from a pet store that was right next door from my place of work. A couple of years ago the petstore closed and there was no other petstore close by. As a result I would buy mice 4 or 5 at a time to last a little while. I have sinced learned only to buy females because the males kill each other.

Today I went to my mice aquarium and found that one of the 5 mice just had babies. I never wanted to breed mice. I don't know what to do.

When can I separate the mice and the babies?
How can I tell which one is the mother? (My snake needs to eat and I don't want to feed him the mother)

any advice to a beginner would be appriciated.
