Re: Hive swarming
"Does anyone out there have any ideas why???"
Temperature regulation and the inability to remove dead larvae and pupae. Don't use screened bottoms. Place in the shade (move to a sunnier spot after the bees are established). Leave a one to two square inch entrance. Put the queen in a queen cage if you can or use a piece of queen excluder over the entrance for 3 or so days. Don't try to save too much brood, but have some open brood in the hive. Put a wet sponge in the bee vac while you are transporting the bees. Do not give up.
Work in quiet fashion and eat your own bread.
