I am wondering if Nosema is contagious?
I have three hives. I just opened them for the first time after a cold Canadian winter to put in some pollen patties, and noticed that 2 out of 3 seem to be infected with nosema. They are weak colonies, and I don't think they will make it. The third hives is healthy and strong.
I've done some research on the internet about nosema but it is unclear to me how contagious it is. Should I move the two infected hives away from my healthy hive?
