Need help with winter covering.
So about 2 weeks ago it was below freezing during the day and below freezing at night so we put a winter bee cozy sleeve on (The black insulation sleeves) and some hard insulation foam. Then today it got back up to 60 degrees which is not normal for this time of year but anyways the bees are out and about. There is no food for them outside but there are pollen patties in the hive. What do I do? Are they overheating? I dont think I should do an entrance feeder but I can if you think I should. Should I remove the foam and leave the winter cozy on? Thanks for the help I am really worried about them right now.
