You should be able to see the welded wire stapled to the outside of the windows in a couple of the photos.
Additionally, we buried 24" wide hardware cloth around the entire run stapled to the bottom 2 x 4. We have foxes and raccoons here in Western Mass.
I do have 1" by 4 feet air intakes at both of the soffits (covered by 1/2" welded wire) and the ridge vent under the metal roof. Is this ok?
The 4 windows are sliding lexan and can be opened a little or a lot.
Just finished my coop. Copied from Carolina.
