Since you only have three, I would just pack all three up like you were shipping them. If you don't have a shipping box (I always save mine) then you can just put a bunch of shredded paper or cotton in them and tape some heat packs to the lid (put them in pillowcases). Another idea is put them in a cooler, in pillow cases and do the same thing. I use my incubator when the power goes out. I put them in pillowcases/bags put them in tubs so they don't fall, and fill the batter, an old fridge, with bottles of the hottest tap water I get. When I do that I can keep the temps at ~90 for 8-9 hours. It's perfect. I also keep a zillion hot packs around and put them under the water bottles if I'm going to be gone all day for work/etc. Whatever you do, make sure the snake cannot touch those heat packs, the big ones get to 150-160+ degrees.
I live in Iowa, and we are getting prepared for this hell storm as well. It's only been snowing for an hour and we already have a few inches of snow and you can't see very far!![]()
