Hi Trish & thank you @Dawn_SD . I never add any ventilation to any of my hives, no matter how hot or humid it gets. It’s only since joining this forum that I started paying attention to the size of my entrances. I’ve discovered that the best performing colonies are the ones with smaller entrances. So therefore I’ve reduced all of my hives entrances. In fact I’m giving my hives two small entrances. One on each side, you’ll get a clue from watching City of Bees as to why I give the bees two entrances. I wont spoil it for you.
That excellent old video needs to be watch several times, so that we can fully understand & appreciate what goes on inside a hive.
Just a short story: I was reading in my ABC to XYZ of Bee Culture how that bees are de-watering the nectar on the return trip to the hive, by holding a drop of nectar in her mouth-part, exposing it to the air.
In that video, they show a bee flying back to the hive. If you look closely, you can see a glistening in front of the bee, which I believe is the bee de-watering nectar on her way back to the hive.
