I am planning on several plexiglass slider windows like I've seen on here. I would prefer that the plexiglass be on the *inside* of the coop. However, I don't know how to work around water getting in on the window framing. My original thought was to staple hardware cloth to the framing on both sides of the framing at the window areas during construction. Then lay the siding over that and nail it as usual. This would make hardware cloth flush with the exterior of the coop. On the inside there would be a second layer of hardware cloth and I would attach top and bottom slider wood 'holders' for the plexiglass, then insert the plexiglass in those and just slide back and forth when needed. So the layers from the outside in would be: siding; harware cloth; framing; hardware cloth; plexiglass; wood sliders for plexiglass. However I am concerned about rain getting in on the framing since there wouldn't be a solid surface (glass or plexiglass) flush with the exterior of the coop. I thought I had seen pictures on here where people had the plexiglass on the *inside* of the coop? If so, anyone care to post another pix (please? ) and/or explain how it is done?
