I was curious to how many of you Commercial migratory beeks requeen all hives every year and when do you do it?
If you do what percentage of your queens/colonies fail by fall?
If you don't requeen everything yearly and just use new queens for replacing deadouts and failed queens what percentage of your queens/colonies fail by fall?
Finally, What do you consider acceptable percentage loss from November-March and also for April-October?
Thanks for your input.
