I hope this isn't a silly question....How many boxes can go above an escape board? Yes...it's all capped honey...no brood. In the past I've only placed the escape board under 1 box at a time...it worked very well. This years production is very good with a couple of colonys stacked seven mediums high(4-5 being honey), so I'd like to do as many at one time as the bee's will allow. Thanks.
