Funny you should ask because I happen know these things since a kid in the neighborhood also had a Brown snake. Feed it earthworms and slugs (occasionally put on repto-cal on the worms). Brown snakes sneak up slowly to their prey, and then they attack, so crickets won't work because they're far too fast for an ambush-type snake.
One time we tried to feed it a small pill-bug. The Brown snake got into position and kept on striking, but it kept on missing because the pill-bug was moving around too much for it to get a clear shot. Surely a cricket is far too fast if that Brown snake couldn't even take down a slow but always moving pill-bug.
P.S. Is it a Midland or a Northern? I don't think there is the slightest difference in care (they're pretty much the same species besides for their different dorsal patterning) but I just want to know.
Thanks so much for the info...I will pick up some worms today for him...glad I asked too as I was going to try crickets...lol
As for Midland vs. Northern...how do you tell? (I will try and get a picture today if that helps.)
