Soo i have been splitting some hives and trying to breed some queens for the splits but im having a major bird issues every time my drones leave the nest which is around 4-5 pm i get like 6-10 birds hanging out on my fence next to the hives plucking bees. Every time i get some queens cups and the virgin queens that emerge goes on flight they are not returning. Im on my 3rd batch of queens cups. Does anybody have this same problem if so what can i do to fix it.
