We are getting ready to build a coop. This is one I was looking at https://myoutdoorplans.com/animals/4x8-backyard-chicken-coop-plans/ Good size for 4-7 birds easy to follow and tells you exactly what you need. It does need a bigger overhang and bump the roof up so you have the ventilation there. Also I would make bigger vents on the ends instead of those tiny round holes. But a decent coop I think.
I had also searched FB marketplace and found 17 bundles of new shingles for $50 TOTAL! They sell for $33 a bundle! The same guy also has a TON of wood and PVC for free that I can have to use. Of course I had already placed my order for most of my wood since I couldn't find anything on FB marketplace. But figure if I forgot anything or want to make it bigger etc. The wood for an 8x8 coop, a roof covered 8x8 run and a hardware cloth covered 8x10 run (so a LOT of wood) was $1400. But that will build my coop and an 8x18 run so with yours needing to be smaller it would be a lot less. Plus I think VT prices are cheaper than MA prices.
