I just finished building my hen house to house my 5 hens. I wanted to build to something that would be movable and yet also substantial enough to give them shelter in the winter. I guess the whole bottom is really a "run" and the loft would be considered the "coop". I used a lot of re-purposed material i had around such as fence panels for siding, cypress for framing, old screen door i but to size, and pallets for the loft. i had to buy tin for the roof, cattle panels for the structure, and chicken wire for the front and added security on the sides. let me know what you think! Couldn't do a video but t hat whole front panel of the loft is on hinges and folds down for easy cleaning.
