During a weekend hive inspection i found that #4 was about to swarm due to overcrowding. 8 frame deep with med super and exculder had at least one capped queen cell & some as many as 4 on all frames in the deep, queen was being attacked and all frames in deep was full of capped brood and some uncapped, med was not even drawn out. So i put 2 frames from the deep in hive #17 which refuses to be requeened with caged queens (this is the one that keeps killing the queens and has no brood now going on 2 weeks). Put 2 more frames in a nuc box that i made up the same day. Put new plasticell frames in the deep, removed the excluder and put super back on. Now none of my hives have excluders on them and i have learned alot about excluders in the past 3 weeks.
