I caught a nother ferel hive from a friends fallen oak tree limb. i hived them last night after dark. the last colony i put in hive, swarmed. this time i put a excluder to keep the queen in place. this morning i went out, and found bees all over the front of hive, and a swarm on a pine tree branch. i hurried to get a swarm trap in place, but they had moved back to the hive box. i checked on them before dark, but they must have gone back in with the queen. i have a 1/1 syrup in place. the lower hive box has 10-frames of drawn comb, with a couple of them with some of ther brood. i guess i should have put another brood box on with only starter strips. how long should i wait before taking the queen excluder off, and put the other brood box in place?
