I should have added to my previous email about being too cold to inspect colonies.
Despite the weather there will be times when the bees are able to fly for clearing flights and to bring in nectar and pollen.
However, the colonies are still building up and will be eating lots of stores.
Keep hefting the hives and if they are getting light then you have to feed them.
Syrup feed is better now than fondant as it simulates a nectar flow.
Only feed about 1 litre at a time and let them eat it all before adding more.
This will stimulate the bees to use the syrup to produce Brood , instead of stores.
That means the risk of any supers getting contaminated with syrup is much reduced.
