Yeah, the wind at my house picked up the anchored portable car port and blew it 1/2 an acre away into our neighbors brush.....it picked up our old Propane BBQ and carried it 3 feet before knocking it over and busting the front glass....it was ruined. I wont be using that. Funny thing is, we use tarp covered kennels as our coops, but they work, and the birds are snug as can be!! We've learned the art of structure and tie down, I tell ya!
If the wind and snow arent issues for you, it might work, otherwise, I think its a very temporary shelter, and theres a reason why theyre free!!
