Looking at the structure of my little, monitor roof coop and considering the repairs/alterations to put it back into use.
I don't think I can lower the nestboxes, because my DH over-engineers everything* and made the mount so solid that replacing it is impractical. But I think I might reduce to two boxes, or even just one, and add a low-level window with top hinged panel for additional ventilation since this property has less shade available than the previous situation. (Note: I measured and the monitor roof provides 4 square feet of ventilation for the 4'x4' coop even with the pop door closed). This proposed window would be below the roost but as far from it as possible -- diagonally opposite the pop door.
If I intend to use it as a broody facility in the future would two boxes be a problem? (And, incidentally, could two broodies be placed in the same facility in two separate, but side-by-side boxes?)
*Over-engineering is a family trait. My late Brother-in-Law was an engineer for the Atlanta airport and we always joked that you could land a helicopter on his deck. My own father thought of anything expected to last less than 50 years as a temporary make-do and expressed disgust at the idea of building anything that would just have to be re-done in a decade or two. Even the 14yo's Lego structures are reinforced so that they can be carried and moved.
