Is there a queen present?
Yes, she was at the center of the ball. I saw her go down into the frames.
Do you have a frame of brood you could give them?
I'm pretty sure I do. I have 5 other pretty large colonies within 100ft. I'll check. I haven't opened them up this year but, judging from the activity and the evening orientation flights there is brood present.
One question about that, Your supposed to transfer the nurse bees along with the open brood, Right?
There isn't enough bees to keep a whole frame of open brood warm at night.
To answer your question 10framer about feeding them, yes, I put 5 medium frames with honey and pollen plus 2qts of 1 to 1 on top in an inverted bucket feeder. All the comb I put in is completely drawn.
