For my first anything, let alone a cutout, I figured there are 70 to 100 thousand bees. There are four openings with bees moving in and out constantly. There are quite a few drones also. I made a video; but am unable to post at this time (?). I built 2 TBH, one is 38" and the other is 48" long. Also built a bee vac with 3 extra inserts (bee box). Would like to do this tomorrow but will wait til monday. After reading other first cutout stories, I want to be sure I have all my bases covered. I am concerned about all the drones! If someone would like to "sponsor" me, you would understand my concern after watching the video. Once again, thank you so much for the replys and this fantastic web site!
