I have seen two spotted fawns in December. One in Pennsylvania about 5 years ago and one in Illinois last year. If the doe fails to breed she will come back into estrous every month till she gets pregnant. I also believe that does that miscarry will come back into estrous.

A fawn like the one you saw has a very slim chance of survival in the northern states. The one I saw last December was on a very bitter cold day. It was barely able to move, was alone and looked near death. After watching itfor a while, I decided not to let it suffer any more.
