Not much detail here and I know that everyone has to pick their own battles. I'm only surprised at using PVC in an environmentally conscious coop.
This is a really nice looking coop and it seems to be well built. Be good to have some details of the build: dimensions, pics, plans etc. because folks may like to build this one themselves.
Not much here to show us how it was built or the dimensions or process or anything. Nice looking coop and run.
