I cut two big hickory trees a couple of years ago. The butt logs were frozen inside when I took them to my buddy's sawmill. We cut them up and I brought them home and put them in an unheated part of my garage. Only the ends are sealed. Most are quartersawn boards 1 1/2 to 2 1/2" thick, and vary in width from 4" to 12" or more. There are staves and billets too, some had the bark still on, and I sealed the backs of the ones that didn't with shellac. The only checks I saw last time I looked was in the center of a couple of the widest boards that were taken from near the center of the logs, and they didn't go in far enough to cause me any real concern. I'm going to cut them up anyway.
I would unwrap them and put them in the coolest place I could find with no air movement. A basement, a shaded shed or garage, something like that. Sticker them so moisture will leave from all sides evenly.
You don't want to leave them wrapped in plastic for any length of time. They may get moldy and begin to break down inside.
