I have a small hive of one deep full of brood up to 8-9 frames full. Last week, I just started up a medium on top. I am using the 4" opening.

There is quite an excessive attack going on right now. Should I get suited up and go change the entrance reducer to the 1-2 bee opening size?

Also, every now and then I have seen bees try to enter my screened bottom board area from the rear of the hive. When I pull out the plastic drawer, there are a few dead bees on it. Do you think there is an area of the screened bottom that has too big an opening? Could it be defective? I have yet to look...
