This my second year beekeeping. Last year the hive never attempted to swarm. However, now I can see at least eight queen cells on two bars of comb. They're all on the side of the comb next to the observation window located from the top of the comb to about half way down. There could be more but I haven't removed the bars to look between the bars. The bees are a lot more tempermental since they started doing this. Is it normal that they would make this many queen cells? Is there any significance to them all being located in the same area? Thanks for your help.
