Well, the mother should make a nest by pulling her hair out but don't worry it will grow back. But if you think the baby's aren't warm enough you can also shred newspaper and put it in the cage
Make sure there is loads of straw round it, this will ensure good insulation. Are there any other rabbits? If so, keep them close together. Also, depending on the temperature where ever you are in the world, you may want to take the hutch inside. Blankets are always good, but could suffocate the poor thing. Is it a newborn? Like was it born from one of your rabbits at your home? If so, I think you should really try hard to keep it warm, but if it doesn't survive then that is just fate. Survival of the fittest.
Use cotton, like old t-shirts, towels, or old sheets). Cut them up in smaller squares and change them daily or when soiled. Put enough fabric int he cage so that the squirrel can cuddle up inside to stay warm. Get a heating pad/lamp. Make sure to leave room in the cage for the squirrel to move around if they get too warm.
Put it under a lamp any time possible. Especially when it is asleep
I found a baby blackbird and what i did to keep it warm was to put it into cotton wool then put it in your bra so your body heat keeps it warm.
listen. I don't know how old you are, but squirrels have fur. That keeps them warm through most climates (weather).
