Put swarm into a KTBH this spring. Gave them 4 combs of honey from my freezer, added furthest from entrance. They were growing slowly (built about 5 combs in a month) so I added 3 empty bars between the brood nest and honey. A week later seeing they had put nectar into at least one of those added bars, I added one more. Last week I inspected and they had converted all the combs of honey I had given them to brood. In fact, the now have 14 combs of brood, mostly capped, starting opposite of the entrance (front of hive to one side), then 5 combs (some only partially built) of bee bread and nectar. That leaves about 8 empty bars. Did not see any swarm cells.
Flow here peaks with blackberries which will be done in a week. Starts slowing down and no fall flow. It seems the bees are building up too late for the flow. They have zero bars of capped honey. Is there anything I should or can do? I don't want them to swarm but there is no excess honey to take from them at the moment. With that many mouths to feed, I am not sure I will be able to take any honey this summer. Beekeepers like to go into winter with about 15 combs around here, but I am not sure of those 15 how many ought to be honey and how many ought to be brood. Thanks.
