So in my area of deep south Texas, lot of Mexicans don't even have coops. They have a enclosed run with part of it being under a roof.
One thought I was a crazy gringo for building houses for chickens. 😁
For me it provides security.
The run is not completely secure.
I had an possum dig under the fence before.
The other thing was that when one hen went broody and was allowed to hatch the eggs, she slept in the corner with the chicks.
She did not go back to the roosting bar for about 8 weeks...
