I just split and made up some mating nucs Wed. They were due to emerge Friday. This morning I went to inspect and see if they emerged. When I got up to the first hive I noticed it was fighting away robbers. I am sure now, because everything was trying to get in, wasp, yellow jackets, hornets and even flies. I peaked in the top and noticed the jar had leaked. It was syrup mixed with hbh and megabee.
I replaced the soaked bottom board and moved it 50 feet away. I setup an open feeder about 300 yards away hoping this will help.
The nucs are ten framers with dividers (3 in 1). A 3/4" hole at the bottom for entrance. I am wanting to setup screens but worried about her getting confused. Will she get back in if she is out during screen install? Will she get back in if she had one flight today and needs another after screen install?
