Early in March 2011 I added a half super with a queen excluder. I just checked my hive on May 3 and the bees had not even begun to build comb on this new super.
Before adding the new super, my hive was completely full of bees and all most all frames had been built out with comb. The hive was started from a swarm in August 2010 and has been thriving until now.
Any thoughts on why no honey or even comb building?
