We have ad some warm days then cool nites, then rain and cold. the bees have been bringing in pollen on and off for the last few months. Last nite got to 29 degrees or so. today is sunny after a rainy Tues. Checked on the hives and the lost alot of brood! the one hive-bigger one- has a pile out front and the other has a small pile! this makes me so sad!
