My strong hive #4 swarm on March 24th. I caught swarm making hive # 1 for me..(replacing a die out). Swarm had mated queen and already drawn comb to work with. They immediately began working hard. Within a few days they had several deep frames beautifully full of eggs. Today, April 18, 25 days later, they just swarm. That was this morning.
This evening same thing happened to another....
On March 31 my hive # 2 swarm. I caught and began hive #5 (another die out). They as well came with mated queen and immediately began working and filling old drawn frames. This evening they swarm, only 18 days later.
Both swarms were seen from beginning to end so I know positively which hives they came from.
Is it normal for such new established hives (by caught swarms) to swarm again themselves so soon?
Would the new swarms be taking the original mated queen or virgin queens? I checked both hives they left, both still have a good number of bees and about supers were about 70 percent full of capped honey and nectar. So out of room I do not think was a factor.
Just seems odd but I really have no idea, is this normal behavior?
