Can someone ID this snake for me please?

Hi everyone, I am new to the sSnakeSs forums. I have many reptiles. Bearded Dragons, Chameleons, Ball Pythons (and other snakes), and Chinese Water Dragons just to name a few. While I was at work earlier today (I work in a pizza shop) I found this cute little snake back in the storage room on the floor. Normally I would have just let him go but its a little cold outside and he seems really tiny. I think he tried to find his way into the store for a little warmth or he was hungry. I have many feeder insects (crickets, dubia roaches, mealworms, silkworms, etc etc and pinky / fuzzy mice I feed to my snakes). So I thought I would bring him home and put him in an extra 10 gallon and give him something to eat. Thing is, I feed all my snakes rodents. This little guy looks too small to even take down a newborn pinky. So I am not sure what I should feed him. Any help on what type of snake he is and what I could feed him would be a big help. (By the way, I am not sure if this matters much but I live in Greensburg Pennsylvania) Thanks.
