I like to thaw them overnight and heat water in a crockpot and feed...(i dont use the crockpot for anything else) but keeps the water hot no running back and forth to get hot water
I set mine out the day before in the fridge, then thaw them in hot water 10-15 minutes before I'm to feed so they thaw out even more, then right before I present them to whoever's eating I heat them up with a hairdryer to ~100 degrees (temp gun) then give 'em to the piggies.
I take the rodents out in the morning and leave them in the warm reptile room. Go about my day, and by the time it's evening and it's time to feed the rodents are thawed and have a natural temp of about 85 all throughout. Then I hit it with a hair dryer!
From freezer straight to a sink of hot water. Roll em up in paper towels to dry and feed. Although I'm going to start putting them in the fridge during the day now and then into hot water.
A room full of empty racks and thermostats that have been unplugged.
