One of our Silkies, Emperor, recently had four babies, and due to the cold right now where we live, we decided to keep them inside. This morning when I checked on them, one of our babies had gotten completely stuck in their mother's feathers. It took quite a while to get them unstuck. Last time we had babies, a fair few of them broke their necks and we think this might be why. Any advice for making sure that doesn't happen?
