I put 4 frames of drawn comb. There is one empty frame with plastic foundation. When I opened it this morning to put those frames in it (It already had one full drawn and one empty in it) they were building burr comb on the lid of the box. It already had eggs in it!

They are geared to make a new home fast. They have a queen needing to lay eggs. Swarms are fantastic to get that foundation drawn.
