Your guys' ways sound so complicated! lol. Microwave, baggies in hot water, heat lamps.
I used to go right from the freezer into hot water, but had a super poor feeding response.
After trying a crap ton of methods for our picky eaters (who had gotten hooked on live because they went on feed strike), I finally figured out that 1) they prefer ASF, although I'm going to try switching to rats and 2) they don't like them wet.
So what I do, is ration all my feeders into ziplock bags to go to the freezer. When feeding day comes, I pull a bag out of the freezer before work & just let the bag sit on the counter in a bowl until I'm home so they're 100% thawed & floppy. Then I blast them with the blowdryer for 1-2 mins and feed! Easy!
