Here is a picture of our henhouse which was built almost entirely of salvaged materials.
In the fall before it gets really cold, I like to start winterizing my chicken houses. I cover screen windows with “storm windows”. I get out of storage the pieces of Plexiglas that I made a few years ago for that purpose.
Each window is custom fitted with a “storm window”. Therefore, to make it easier to install, I used a permanent marker to write the location of the window that it fit over.
How to tips: Measure and cut out pieces of scrap Plexiglas. I used a box cutter and a metal ruler to score the lines. Then I snapped it over the edge of a work bench. This primitive technique works well enough for chicken house window covers.
To attach the Plexiglas, pre-drill holes making sure that your exterior grade screws can freely fit through. Plexiglas will start to crack if the drill hole isn’t big enough. (See crack at the top of the window in picture.)Use the kind of washers that are rubbery. That way you can get a snug fit without stressing the fiberglass.
In the spring, I remove these window coverings.
