I have 3 queens coming this Friday 4/19. Our forcast here in SE South Dakota is for high 40's and cloudy for this coming weekend. I'm concerned about it being too cool to open the hives. Does anyone have any advice on requeening in cool weather? I was thinking about asking my supplier to wait in sending them for awhile. Note: I had determined that 3 of my hives were queenless, no brood/eggs. When opening the hives the bees were very loud as though queenless too. I thought I would try and introduce a queen to these because they all had a lot of bees. John
