Re: Is it possible to put swarm back into original hive?
You can stack both the hive and the swarm side by side with queen excluder on top of each one. Then stack up the supers centered over both. You'll be able to keep both hives and get good honey for yourself as well. You'll need a couple 8 inch wide boards to cover over the top half of each hive that is not covered by the supers as lids over the exposed excluders.
I've been keeping a few hives for the past 20-25 years, and no longer treatment free as I got tired of the losses.
