Seems logical, as there seems more chalk brood in the early spring.
I have two questions:-
        1 Is there any correlation between damp hives and chalkbrood. I find on
adding ventilation it (chalk brood) is reduced or eliminated.
        2 Why do we requeen, when it has been proved that it is not genetic.
Comments?
