Last year was my first year with bees. I had 4 hives. Three were in the shade most of the day and one was in full sunlight except for one hour in the evening. The three in the shade did not build up very much at all and the ones in full sun were exploding with bees. I have a similar situation this year. Is this just a coincidence or do bees do better in full sun. We don't have a worry here with shb so the shade is ok for that.
