As to the nasty bee's, they do say that a second mating of a inseminated
queen colonys can be nasty.
As far as smoker fuel goes, I use rotten oak, dry lavender cuttings and or dry
bay leaves, works for me
I use glass crown boards the hole is covered with a piece of glass, if you put a wire mesh over the hole they gum it up, The hives are on mesh floors so they don't want a through draft.
