I couldn't be later to this thread but we also use the Omlet door and LOVE it. Keeps us from having to worry about our girls seeing the wrong side of a predator at sundown if we're not at home. It was super easy to retrofit onto the wood coop I built a year and a half ago and creates a nice seal at night to keep the cold winds out.i love our Omlet coop door. No smooshing here!
