just wondering if anyone has ever done anything like this. I have a 10 x 10 or a hundred square foot Chicken Run. i am thinking about building a platform that is 3 feet off the ground and 5 by 10 ft. That would give me another 50 square feet in the Run if the chickens used the top of it.. I have a pallet type table out there now, but it's not solid on top. I'm really thinking about doing this more so for just the winter so I would give them a nice Snow free area to roam in. I've got a bunch of used rubber roofing that I could lay on top of the platforms for traction it would actually heat up with the Sun since it's Black. any thoughts?
