I did it. It wasn't pleasant or easy, but I used an uncapping fork on the mostly capped drone frame in one of my hives today. Quickly. I then just put the frame back in for the bees to clean out. The wax foundation was too soft to try banging the cell contents out. The other drone frame in the other hive was now being used to store nectar, so I didn't have to do anything to that one.Some people don't bother freezing, they just scrape the cappings off the frame, knock out the pupae on the ground or to their chickens, and put the frame back in. I have to harden my heart a little more before I can do that (I confess), but I admit it does seem like a more straightforward method.
