Screened bottom boards and swarm?

I have added screened bottom boards to the remaining two Lang hives. Now the only hive without the screened bottom board is the Warre. I will probably add it to the hive as well since there seems to be quite few bees at the entrance fanning like crazy. The temperature is already close to 90F during the day. The screen should help with ventilation and hopefully with the hive beetles as well.
I've added Beetle Jail to all three Langsroths to eliminate as many of these invaders as possible.

it appears that the new hive (the one that was a control to the split) lost a large number of bees. Swarm? There were at least three empty queen cells. The population seems to be halsf of what it was when I brought it in 4 weeks ago. Also there was one frame with stick eggs, but no brood anywhere.
that is what i get for leaving them alone.

Warre buildup continues, strange activity around queenless hive

The comb buildup in the Warre hive is coming nicely. The top hive is built up and activity moved to the lower hive. The bees are drawing the comb in the center 4 or 5 top bars







There was a lot of strange activity yesterday when we came to the bee yard. The bees were really active around the queenless hive. They were also quite aggressive. I thought that they were ready to swarm, which did not make sense since they had no queen 3 weeks ago.

I smoked them and opened the hive. There was no sign of a queen, no eggs, and one possible empty queen cell
The bees quieted down after my disturbance.

I was able to capture a bee burial. I did not know that bees would go to such lengths to clean the hive. The bee dragged her dead comrade at least 2 or 3 feet from the hive.

Warre buildup

The colony I transferred into the Warre hive is thriving. The top hive is completely filled with comb. It took less than two weeks.





Girls already started buildup in the lower hive as well.
They got rid of ant infestation by the morning after the storm.
The moat I built (plastic tub filled with water) probably helped too.
