Was in my hives today to remove some grafts and make some splits. I was getting into one hive to get some brood and found 6-9 queen cells that were made in preparation of swarming. Lucky enough I caught them before any had hatched (some still had not been capped) so I decided to split this hive up and use all the queen cells for my splits instead of using my grafts. The reason I did this was because the queen cells made in preparation for swarming were so much bigger as almost as much as twice the size of my grafts. Why is this and how do I get my grafted cells to look like this? Or is that even possible because of the difference in forcing queen rearing on a hive versus the hive queen rearing naturally.
