Swarm under my hive
I checked my hives the other day and noticed a large amount of bees(equivalent to a 3pound package) under one of my hives. They are located right under the solid bottom board right in the front. This is one of my strongest hives that is doing very well. I smoked them lightly and none of them retreated into the hive. After more inspection I noticed they had a large amount of comb built with nectar. I did not see any larva or brood. This all happened in a matter of days. Is this a swarm from the hive above? Should I try to capture them?
