One of my hives is literally busting..today it almost hit 70F and they were out in full force. It consists of four 8 frame mediums of which 3 are full of bees, pollen and honey (some eggs though no capped brood yet). The bottom box has no stores but was moderately full of bees. In a 1 mile radius from here the foiliage make-up is about 40% forest, pasture and cropland and the rest is apple orchards. Should I be scrutinizing (for swarm signs) my hive(s) during the apple blossom bloom or is it still better to time a split with the first traditional big flow that occurs when the tulip poplars bloom a few weeks later?
