I recently checked on a colony that was in a house wall in November.There was a total of 4 colonies in this old house and 2 of them I have successfully cutout and transfered.This colony was in the back of the house in a wall and occupied a space of 2 feet wide by 7 feet tall(a very established and strong hive).I checed on them today and nothing,no bees,no honey,no brood,eggs,nothing.The comb was all there but it was very briddle like potato chips.It was wierd that there was nothing there,not even dead bees.Any thoughts?
