Re: New beek in drought
I would advise leaving them be the way they are until the drought is over. If a fall flow brings in enough to need a super, then super then. If the fall flow is not strong, then just leave them be to get packed in with honey for over wintering. I'm guessing that the weaker one won't need supering and the stronger one you may get to pull off the super of honey for your dinner table dessert. I'm not sure of course, as I'm not familiar with your area weather and flows.
20+ years, raise my own queens, feed when needed, I treat but have not perfected varroa management yet.
