So I'm not new to bee keeping, nor are these my first hives. In my 3.5 years of beekeeping I've never had a hive survive winter. This year I have 3, 10 frame hives, 2 deeps on all and one nuc only one brood box. All boxes are deeps. The 3 10 framers are very strong. The nuc is ok, could be better, could be worse. This year we (my sister, bro-in-law and I) had decided to not harvest to give them the best chance of survival. All have been treated with apivar strips already. I am thinking of an OAV treatment before it gets too cold.
Is this a good move? Bad move? Or really doesn't matter.
