Thanks everyone!
We have a tub of 4, 3 females and a male and I've had zero issues with them. There are two litters in there right now and one on the way :3 They're all taking care of the babies and it's going awesome XD

I check their water every day so I don't think it was lack of water. It may have just been a first time issue. If she does it again she's gone.

I've finally got rats so I'm gonna start breeding rats instead. They're easier! And they're so cute and fun to play with XD
