My babies are right at 13 days old. Mom is in a hutch cage with a wire front and a solid room hutch on the back. Up until now the babies stayed burrowed in the nest but now they are running all around inside the little hutch. Tonight it will get 31 outside. It has been in the low 50s. I have never desturbed the nest and I don't know what to do. If the babies were still burrowed down I wouldn't worry but the nest has been trampled flat. Will the babies all pile up and stay warm or should I bring them inside. Will Mom take them back in the morning if I bring them in?
