What's the most efficient way to get a colony to draw a lot comb? I realize that comb, building is most intense at the beginning of a season and then tapers off. Is it a matter of having the right amount of bees? I can feed throughout the whole season, shake bees from other colonies, add frames of brood if needed. Or vice versa, I can take out frames/brood/bees. Would replacing open brood with capped brood help? I can dedicate a yard for this and I'm not looking for honey production from those colonies.
