Robert- we were gifted our TBHs by a quite amazing wood working grafts person who was also our initial mentor. Not sure exactly where he got the plans from but they included narrow end facing holes 5 each and standard wine corks fit to close them off as the weather turns. This is one of 4 hives with that design and is actually the furthest away from the other three by a good 100 feet and stands by itself. FULL hive front to back with brood and honey comb and started as a successful blind split middle of April. The hives have a hinged lid with pitched roof vented at each end AND a handle on top with a vent ridge directly under it. Bottom screen and sliding sticky board also there. This spring I put a 1 1/4" thick board on the stands and then lifted the hive off that by 1/2" for summer ventilation. The theory is once we are done with the hot weather, the stickers will be removed and the hive will sit on the thick board, but the sticky board can be removed for OAV, or I can prop the hives back up with the stickers and OAV that. I doubt any of that is causality. It is the only hive of 4 with that design where the bees have done this, and only started/completed the task in the last 72 hours. Busy as bees absolutely. Will be watching to see if they close off the one completely and/or start closing off others.1garysaccount "to single bee at a time." I am very curious as to how you ended up with holes for bee entrances??? I changed about three years ago to a thick, plastic plate. Through hoels are just large enough for worker bees with pollen, including drones and appraently slimmed down queens trying to swarm. I did this to manage robbing, prevent mice intrusion and allow easy OAV heater installation by raising the plate ( slotted holes). I have been very happy with the design.
little john- thanks and indeed go figure. Definitely not going to undo what they felt obligated to do. Just going to watch to see if they shut things down on their own. If they do, depending on how much entry ways they left, I may not close off any come our version of winter.I've seen exactly the same 'entrance reduction' with a couple of 5-frame nuc boxes - so it does happen sometimes. And yet it's not happened with dozens of other hives with the same style of entrance (ALL of my hives have 22mm (wine-cork size) holes for entrances). As you Americans are fond of saying: "go figure".
Hiya - as well as those 5-frame nuc boxes (photographs of which I've mislaid) seems this also happened to another box, which I'd completely forgotten about.little john- thanks and indeed go figure.
