Glad you didn't lose them all. And btw, partial defrosting in the freezer with containers unopened is WAY better than when people thaw & warm up prey to
feed, then try to re-freeze it. The longer prey is at room temperature (or anywhere close to it), plus being handled (ie. more exposure) the more that "germs"
have a party & spoil the food, whether it's ours or for our snakes.
