I think that Taylor mentioned in his Bee Culture column a couple of issues back that if you leave the bridge comb intact between the boxes, the queen will make her own way back to the bottom box and you won't need to reverse. I'm trying it now and it seems to be working with most of my hives; the cluster has moved lower and the bees are packing away my feed in the upper half of the top brood box. chris Chris and Janet Sauer Colesburg Apiaries www.greathoney.com (319) 856-2015
