i'm very new to beekeeping. i've been reading lots and lots of info trying to help my level of knowledge bypass my lack of experience. i'm wanting to try freezing drone brood to stymie the varroa mites. i understand drone brood is usually in a larger sized cell. how do i get my bees to build strictly drone brood so that i can remove and freeze the entire frame? is there a different sized foundation to use? thinking that, i'm worried that i may have installed the wrong foundations in all of my frames. my bees were on severe back order because i ordered them late. they've been hived for almost 2 weeks.
