I read a lot about upper entrances on the forum - can someone explain to me exactly how to fix an upper entrance? Where to put it? How big, etc? I have never used one on my hives. We have screened-bottom boards on all our hives, but it has been so hot & humid lately that the bees in the larger hives are really hanging outside a lot late evening and night. Right now I have a hive that looks like it's bearding and it's 9:00 pm here now. This hive has a queen excluder on it because yesterday I was finally able to get the super off the bottom that the queen laid in earlier in the year. I have 2 hive bodies, q.e., then the super the queen had laid in, and the honey super on top of that. (I made sure the queen is in the hive bodies) Is that an ok arrangement...for now anyway? I don't like to use queen excluders, I guess because I really don't understand how to "correctly" use them.
