i agree with poly hive , not to fussed either way because i have this bee shed thing going on if i wanted to all i would have to do is warm the shed up close the front entrence and when finished give them time to get back home
looked at mine today , no wind 4C bees flying . Inspected bees plus a 3 nuc brood box, gave all extra fondant. Didn't lift out any of the nuc frames but all three compartments bursting with bees. main hives have had inserts inserted for 3 weeks now; checked for natural mite drop, all found to be clear .
