I recently added a second hive body to my new 22 day old colony because they had drawn comb on all 8 frames and they had brood on most of them. I pulled only one frame of brood to pyramid up into the empty box (mainly as a ladder because my frames are foundationless) and I pulled from the middle. I’ve since read that I should have pulled 2 or 3 frames to pyramid up and only if there are enough nurse bees to cover the frames. It went down to 38 degrees that night (the days are warm though). Did I kill those bees or make them work lots of overtime warming that frame? I didn’t know if I had enough nurse bees. I did this 2 days ago. Should I go back into the hive and pull up 1-2 more brood frames to add to the one? Or leave it the way it is?
