I've seen ads for the white fabric hoop structures. I love the light they let in. That is a healthy thing. The possible downside, during summer heat, is heat. But I think some have ventillation thingies, somehow.
I wish somebody could manufacture a pretty fabric chicken dome for suburban backyards. One the howling winter storms and the summer monsoons can't destroy, but lightweight enough to pick up and move around the yard, and predator proof. I ask for a lot.
