Channel: Matt Davey Bees
Date: 28/11/2020

This video shows the 5th Inspection of Opening the Sides of the Brood Nest (OSBN) with Empty Drawn Comb once the Main Flow has started.

In this video Matt moves up 2 Frames from below the Queen Excluder and 2 Frames from above the Queen Excluder into a 4th Box for another Honey Super.

Opening the Sides of the Brood Nest (OSBN) is a Swarm Prevention method.
During Swarm Season:
- Place empty/undrawn frames on the outer edges of the Brood Nest.
- Trigger wax making with a Partial Foundation/Foundationless Frame (OSBN Frame).
- Maintain at least 2 empty/undrawn frames in every box throughout Swarm Season.
- Move honey frames up and out of the Brood Box(es).
- Can start as soon as Drones are being raised.

During Main Flow
- Maintain at least 2 empty/undrawn frames in every Super
