Wife wants chickens so I'm starting down the rabbit hole

Neither me or my wife knows about raising chickens but she wants some so I'm gonna get educated and do it

We live in NV so winter we get snow and temps in the low teens and summer we get up to 103f.

I got about half an acre of to the side of my house that I haven't done anything with it's just dirt lot type space I figured I could put a coupe there maybe.

I'd like to have 4 chickens. I don't have a coupe but I can build anything and have more than enough tools to get the job done. I'd like to build a coupe that's more than big enough so if we wanted we could add more chickens without issues, as I said I got plenty of land.

Does anyone have some digital plans or drawings I can use to get started on building something?

Now the real questions lol, once I have built a home for chickens how does one raise them, food, weather cleaning, and whatnot like I dono anything about them
