I would recommend buying a shed and having your carpenter or handyman do this:

this only will work though if it opens up into some chicken run, they can’t stay in there forever, just at night. remember every coop must have nesting boxes, and roosting bars. If you don’t have anyone to work on your shed, or if the interest doesn’t appeal to you, try Omlet.

Omlet really does here the best coops. they are predator proof. you can add rain, sun, and snow protection, thermal covers, feeders and waters, peck toys, swings and more just from the website that simplest “click” into their spots. the smallest coop would probably work fine for up to 4 chickens, but if you wanted more, the taller one and slightly larger would work better. you should also consider is you want a “tractor”, that you can move around to get them fresh grass.
i do believe that the best solution is to fence out a large area where you have a big tree to protect them that is on grass, preferably dirt (easier to maintain and just scatter some mealworms on there they will love that!) and put a shed if you are willing to. omlet will also work, but probably not as good as the shed. my first chicken setup was for 5 chickens. first, we got a regular coop like this:

That works for about a month and MY GOD it was absolute hell to clean this think. overall, it was just not a good experience. we switched to a shed we got at costco and it worked great.
let me know if you need any more help, or if you need help deciding chicken breeds.
