I had the hinges left over so opted to use them, yes I pre-drill everything for the most part.
The plastic mesh is thick and yes it did work very well. My intention was to put the hinges on later before Winter as plastic would get brittle.
Put in the pop door and strung up rope to the house Window

Now I can just close the door from the house at night.
Will get pics of the door later, here is a pic of from inside the house to the coop.
goes into coop on Right for about 1-1/2 feet, then through eye hook and across to the Left side, Eye hook, then down to door.
Oh you can see on the Right, between fence and coop, is the hay that I stacked behind it. Works great so far and snow will fall over fence.
I want to make that latch with the small hinge I saw on Youtube.
Still trying to use up bits of wood hanging around so I have to fiddle with how to make it and watch the video better
Love this video, but my hinge is on the INSIDE so no hole like this one on the outside.
