Neighbouring land and not my photo but it's dark here now and this is close enough.
But I'm not actually looking for planting or building advice so going to leave it now (not that I don't appreciate folk trying to help

)
Beautiful property... would love to see more of your countryside
Oh, we're a chatty advice bunch... some we can use... some we can't. I like to hear advice even if I toss it out the window

... never know though. My property is tiny compared to folks in rural areas so my circumstances are different.
Show what you finish with... although gardening & chickeneering is never done. I'd love to see how you work out using Nestera... wish more plastic coop options were available decades ago when we were looking for non-wood coops.
Our first coop was wood & OSB board custom-built by a feed store customer. We had to keep it covered in tarp both summer & winter for 4 yrs! Wonderful workable construction design 4'x6' but poor building materials.
Next we looked for more durable, cleaner coop options, but the only plastic coop large enough at the time were Omlet coops & the largest was only the Eglu Cube model which was also not tall enough for us. Too pricey for our budget at the time. They have a much better Eglu Pro nowadays.
This is the smaller Eglu Cube we culdn't afford.
So we opted for a Tuff Shed type coop not made out of wood. We all have to do what fits our property needs.
There were a lot of cracks & leaks from final assembly so we finally had to build a patio roof over it for protection from drafts, hot sun, & rain leaks!
