I really love that design, simple yet really practical!There is ventilation above their heads. The ventilation from the bottom is intended to create a draw. It pulls cooler air from the ground and pushes air upward and out the top. Like a chimney. It can also allow a cross breeze which is important for my ducks in the summer.
You may think I'm totally clueless but I have a degree in architecture. I know how important ventilation is to a structure AND my birds. This isn't my first, second, or even third coop... I've built a lot of coops although this is my first with a cattle panel.
We don’t have those panels here, but I would like to use metal pipe bent to an arch to accommodate some sort of flexible yet solid material for a roof - I think metal roofing in these arched pipes would be too heavy. But some sort of PVC panels maybe??
My run is 16’ wide one side is at 6’ high, and the other side is 5’ high, I thought maybe running 2x8x18 planks for roof joists but the cost of that would be extremely high. My run is about 100’! So on even 4’ centres with purlins every 2’ it would be costly!
Of course using that sort of roof I could get away with steel roofing .
Thoughts??
