I have a Netherlands Dwarf who just kindled her first litter. The first couple of days she covered them up, but now she isn't. It has been pretty cold in the garage and my space heater is not enough for this new issue. Temps during the day are ranging from 11-27 and night is sub zero to about 8 degrees. I work so I can't constantly be out there to make sure the babies stay covered. I have never had this problem, and I am not sure what to do about it. Please help!!!
