I disagree with this - I would really recommend against moving a litter of newborns unless absolutely necessary. Why would you risk it? No wonder they nip you, they are trying to defend themselves and their new babies! Mine never nip, full stop.moustress said:Removing a doe and her new babies to a fresh tank, or the ones still pregnant, shouldn't be a problem either. I'd watch out for your fingies, though, as the new and expectant moms can get nippish.
