Wondering if some can assist here with theories.
I have just put a scale on the hive and it seems to be going well. I have noticed though that in the morning shortly after the sun comes out (1-2hrs) the hive weight has been going up a kilo or two then quickly (over the next hour or two) dropping down quite a few kilo. I have been putting the drop down to the foragers leaving the hive but I can’t figure out why the weight is initially going up. Any ideas?
