Please continue to check that hives have not been damaged and that mouse guards are still in place. Do check levels of food stored since I have noticed a couple of my hives are getting a little light. Feeding options are candy/fondant or some people use a kilo bag of sugar with a 2cm hole made in one side water added until all moistened and then inverted over the hole in the coverboard. Once you start feeding you should continue to do so. In emergency feed sugar syrup either in a frame feeder or directly into an empty comb.
It’s not too late to treat with oxalic acid given the cold weather we’ve been having. Check the natural fall. Over 2 a day will mean some action will be required in the Spring.
