Yeah, I did the same thing with a black rat baby last year. Neighbor found it and the weather was too cold in my opinion to let him go. I brumated him in a seperate room from my other snakes and let him go in my backyard in the early spring. No harm done. Although, if you do have a good warm window, like Doug had said, he should be fine. I just chose not to take the chance because the night temps were getting real low.
