You're such a good chick mama.I made her a like a nest with a towel.
So far when I pick her up she feels warm
Is she still acting normal, eating and drinking? If so, you may want to try to figure out some type of "brooder box" for her so she can run around a little. A cardboard box a couple of feet long and a foot high about would work. She'd need heat on one side and a way to get away from it on the other. You don't want it too deep or it could hold the heat in too much, and too short, she'll soon learn how to get out of it.
You could just lay paper towels down, as when she gets a few poops, those are easy to replace.
