@ GMS actually it is a real sceen except her. My chickens live in that house 24/7 all year around.

The plastic is not your typical it is a poly weave for greenhouses built with 2x4's, 1 inch galvanzied tubing, and heavy 1 inch wire. I have raised chickens, guineas, turkeys, and rabbits in there for the past 7-8 years.
As for the smell it is only bad in the winter when the humidity goes up and I do not put enough straw in the house.

As for the summer the sides roll up for air circulation.
Actually, my partner thinks I be babelicious

and I am the one who cleans out the chickenhouse.
I will post a summer picture once I finish a few things. I have since did some erranging inside.
