finsky, i froze my extra honey frames last year also. i had room in the freezer and it was a good place to keep them and keep ants, moths, and whatever, out of them. when i fed them back, i just took them out the night before and put them in the hive the next day. this was very helpful when we warmed up late winter, but there was no food for the bees. their own supplies were low by then and this gave them extra to see them through what turned out to be a wet and cold spring.
