Thanks guys. This is my second set of quads born here and I often have triplets born as well. ChinnyMom is right about how many kits they have. I think the highest number I've ever heard of in a litter was twelve back in the 60s or 70s. I don't really known how many of those survived though.
Dynasty's doing well with feeding them. So far, all but one have gained weight and the other is holding steady. I've only seen two squabbles and those happened because a clumsy kit accidently bumped into a sibling while walking by. They've been pretty good about sharing nipples and are even using the ones between her rear legs.
I don't have any other nursing females right now. However, I have quite a few that love to take care of babies even if they don't have any of their own at the time, so if I need to rotate I can always put some of the babies with one of them to be watched. I've also got everything ready in case I need to hand feed or supplement the babies a little bit.
