Mine are making brood and should continue until they go into their cluster for the winter < 40 - 45 outside. At present they are consuming 2 gallons of 3:2 and 1/2 of a pollen patty a week from a top feeder. This also will drop off about a week or so before they begin to cluster, then I remove the top feeder and replace it with a patty of fondant. - Mike
