Look at the coop design page at the top of this page. It will help a lot.
My concerns after looking at your video....
1. Metal building. Metal does not allow condensation to leave. You may have too much humidity in there. I have a metal roof on my main henhouse, and humidity build=up is a constant problem. (see my BYC page for my recycled buildings)
2. Why would you put them in a cage at night? Just put up a 2x4 roost along one wall with a cleanable poop board under it, and you have yourself a sleeping quarters for chickens. Add a few 5 gallon buckets on their sides, and you have nesting boxes for eggs.
3. I LOVE the window for a pop door idea!
4. Don't even think about closing up the tops of those walls! Put hardware cloth over them for ventilation. (See #1) That building is gonna be a hotbox in summer and much too humid in winter...you will need all the ventilation you can get!
