i have been asked to take bees to a land lab wed. it is going to be in the 90's. i have been promised a place in the shade but i am concerned that the bees in my 1 frame med observation hive will cook. the event is from 9 am till 3:30 pm. is it better to put a frame with lots of bees in thier(more cooling force) or less bees ( less to die)?
