Hey Gang...I ran across a very small Brown Snake while out walking the other day. It was warm the day prior and think he got caught out in the cold when I found him he was nearly dead. I brought him in and set him up in a small tub with some water. He has since perked up and I would like to feed him a few times before releasing him back outside (and after the temps get a little warmer - was 35 last night)

My question is what should I feed him?
Research just says insects...but which ones?
He is barely as thick as a #2 pencil so it needs to be small.

Thanks for any advice.
