I attemted to raise at least about 100 queens weekly, but mean while my own bees went to hell. Normaly, I requeen all my hives in the spring with the queens that I raise, but this spring was a real challenge, and let down. While raising queens for others and trying to fill the orders, most of my own colonies swarmed. What a loss! What do most large scale queen producers do with requeening their own operation? Do they requeen in the fall? Does that cut down on spring swarming?
Thanks, and best of wishes.

Jim.
