That’s interesting. Its only been five or so days. A few of those were windy and wet. About 12 -15oC but the last two days have seen temps go right up 25oC +. I have one completely empty frame or wired foundation almost in the middle of the Brood box I will wait till they start getting this drawn and laying in it before adding my Super. Some bees will dive right into any part of the opening, I have been very impressed with my Cornish Black Bees flying ability even in strong wind and mizzle.
