I have one californian doe who is a CRAZY protective mother. She gets nervous anytime I try to come near her, but before then was fine. She grunts at me and smacks at me with her front paws, even though the babies come right up to the cage (since they've been handled so much). My other does could care less if I come in and mess with their babies. SO, I think part of it is just that some does are worrisome mothers. Just do you best to not stress her out... I try to always give my doe a little hay or something that she likes when I go in, so she doesn't always think I'm trying to harm her babies.
