I have 3 top bar hives.

I was out of country for a few weeks.

Neighbors let me know several swarms while I was away.

Last weekend, I opened one hive and saw brood and found the queen.

Just checked on them this afternoon.

Every bar in all three hives is full of honey. No brood. I did not spend time looking for the queens.

I added a few bars in each of the brood area today.

Do I need to more thoroughly look for queens?

Do I need to remove the comb that has honey in it in the brood section and replace with empty bars?

Any idea what is going on and what I need to do?
