I don’t have any experience with this coop. But I wanted something similar as rain/ snow protection. I found this and they look similar. Just one has wire and I think that would be pretty easy to add.
My sister raises her broilers though in something like this. But I think she made it herself out of an old hoop fabric garage thing. If you get what I mean. https://www.backyardchickens.com/threads/a-cheap-rain-sun-snow-shelter.841309/
