Make sure to leave her nest alone for at least 3 days, even if you think she's done and none survived... apparently when stressed she can delay birthing for days- found that out this winter. I'm glad that I brought my doe in after seeing the one dead, she was outside because I didn't expect babies. She had 3 alive the next day, then another stillborn the day after that!
It was also the messiest kindle I've ever witnessed, don't panic if there's blood on her fur, as long as it isn't dripping.
PS: If you can find some willow branches, it'll help her with inflammation. Also free feed her favorite treats, especially high protein- if she doesn't eat the messy stuff she will need as much energy rich food as she can get.
