I have seen that several of the castle's offered for sale state that they have a vented bottom board. Anyone know what they are doing for venting?
I have not seen the ones being sold, but the one I made I vented by drilling a hole and putting wire mesh over the inside. I vented front and back and also a screen covered hole in the plywood cover over each section. If it is cold any or all can be covered or plugged. I did not vent the bottom....Jim
The one Cedar Glen Bee's is making (Pat. Pending)* has a SBB with a solid plate that will cover it. Unfortunately you have to take all of the divider boards out to remove the cover. It also has 3 frames per compartment and the feeders are designed into it.
* Did you know that Pat. Pending is the worlds most productive inventor? His name seems to be on every new item that comes to market.
