Hi there, everyone. I am new here, and I need your help As soon as possible!

I found a snake today that I did not expect to see. I am not sure of the species (Pictures below), but I do know that it is not venomous and it is very small! I want to say it is a Northern Red-Bellied Juvenile. I found it wedged between a rock. I live in Northern Virginia, and it has been in the 40s today. I know that snakes are reptiles, which means they are cold blooded. I am not sure how he has survived, but I do know that he is moving very slow. I have put him in a large container in my home. I don't want to let him go unless I know that he would survive in the cold weather. If I end up keeping him until it starts to get warmer, what should I keep him in?

Thank you,
Boomslang (Jeremy)
