>SO I'm going to take a wild guess and say, if no bearding is seen on the hottest days then it either means there is plenty of ventilation and or there is too much ventilation.
I've never been sure what it means when there is no bearding. Maybe it's a good sign. Maybe it's not. At one time that was my goal. More and more I'm suspecting that bearding is normal and maybe if I get them not to beard I may have made things harder on them...
Being a second year beek I have observed that when you add a super it tends to help cool the hive a bit or at least keeps them inside a bit but shortly after the bearding builds back up with the temps. Amazing to see what seems like half the hive hanging out the box right now with temps in the 90's. The least stronger hives don't beard as much until numbers increase.
