Went out to look for queeny on Saurday. When I get there and opened up the hive they were ALL up in the top where all of the last year's leftover honey was. There was approx as many bees as where in a 3 lb pkg. Anyway about 2 weeks ago I put then all in the lower part of the hive(where they should be) and Satuday they were all back up in the top. What gives? Oh and I don't think that I ever did find queeny(didn't see any eggs of brood either). Should I gas 'em and start over w/ a fresh pkg of just re-queen?
