Here in New England spring weather can be all over the place 50’s one day 20’s the next. In a local forum there is discussion on pollen feeding. My take is early pollen feeding can stimulate brood and if followed by a cold snap could result in a lost hive due to the bees refusing to leave the brood in order to cluster. Others state that bees will never have more brood than they can keep warm and that this is not an issue. These are all hobbyists so increasing early populations for pollination or honey crops don’t really come into play. Am I wrong in my thought process ?
