she will be fine dont panic captain , when you take her out you can tell by looking at her teats that there feeding off of her, they will stretch and in large , if you cant hear them squeaking its because they have not long had a feed and are flat out a sleep. give her plenty of milk and dont feed her raw meat as she will stash it in the nest and you will get maggots in the nest. i feed biscuit as well. avoid the nest if you can but i check every week to make sure shes cleaning them nicely you can do this without any contact , but make sure shes not around as more than likely she will nip you,
