Queen Bee
My crown boards do not have holes, my Feeder boards have holes and my clearer boards have holes but i don't use nor do i like the multlipurpose combined crown boards/feeder boards/clearer boards sold by the main retailers as "crown boards"
My bees including Nuc are on Open mesh floors with the varroa board removed ALL YEAR ROUND unless i am monitoring for varroa drop
in winter I insulated the space under the roof and above a solid crown board and the space ABOVE the insulation is vented via the roof vent, i use no other ventilation like matchsticks under crown boards if i am on open OMFs
i have various extracts from Beekeepers Annuals by B Mobus on the subject of ventilation but as they are copyright of NBB, i cannot post on the forum . howerever if you wish to see them for your own personal use, please pm me ( photo attached)
