Crackling sound in Hive.
I too today started to hear that crackling sound coming from my Hive. Searched the net for info, this and one other forum were all I could find on the Topic. After reading a few posts about chewing, I went and studied my Hive very closely, and sure enough, there were bees chewing on the inside of the Entrance reducer opening. They must want a larger opening. I guess they know best, so I removed it and no more noise.
