Need Info For 13 Unidentified Hatchlings

Well I live in Wisconsin and I was out and about the yard and discovered a pile of snake eggs next to the fire pit and rather that letting them get destroyed I brought them inside and stuck them in the incubator. About 2 1/2-3 weeks later when I opened the box to candle the eggs, 13 little hatchlings tried to get out of the box.

First of all I have no idea what they are. Unfortunately when you google wisconsin snake species you really only get pictures of adults or older hatchlings. They hatched out a solid steel gray color with bronze undertones, white bellies and about 4 inches long. A few of them have opaque colored eyes so they will shed soon. Now they are about three days old and a faint speckled appearance is beginning to show on some of them. With some more heavily speckled than others.

Second I am not sure when they will want to eat and what to feed them. I raise mealworms and blatta but I'm not sure either of those will work. Pillbugs maybe? I heard most hatchlings eat after their first shed. Is this true?

Any information would be greatly appreciated

Pics would help a lot....
At 4 inches, and that color, I'm almost inclined to start the guessing with ringneck snakes; but I'm not sure about the white belly part (I don't remember them having a white belly, would have said yellowish)
There are some other possibilities, too.

Idk how to post with my blackberry...

Do they have a little ring around the neck? (in some species, the ring is yellow...sometimes fairly faint)

No ring, just faint speckles on their backs.

Could be a Dekay's snake, then.
Small earthworms would be your best bet for feeding (I know the ringnecks eat red efts and other small salamanders, not sure if the Dekay's do, too)

Hmmm that's getting closer. I bet I'll be able to see better after they shed. Maybe they'll develope a pattern then. Will they take food now?

Have to rule those out though, Northern Brown snakes (aka Dekays) are live bearers.

Yea I just googled them. Dekay babies also have rings around their necks and are smaller, 3 1/2 inches.

Forgot about the egg part for a minute - I'm back to wanting pics
