6a 4th yr 7 colonies inc. resource hive
2nd year- (correcting mistakes from 1st year)- lost hives last year partially due to YK predation. So this year added robbing screens straight away to nucs. Really impressed so far with use and noticed a Bald Faced Hornet on the face of one of the robbing screens the other day. Since the robbing screen didn't allow it direct access the bees had time to launch their attack. I'm also noticing a few YJ's and one Bald Faced Hornet dead out front. Strong colonies can defend no matter, but this is giving my start ups an advantage.
