I took more pictures hopefully that helps. The run is 13 ft x 7.5 ft so about 100 square feet not counting the area under the coop which I think I will fence off because something was/ is living under there. One of the drop down door is really rotted so I think I will replace that and try to make a double door instead that opens outwards rather than down that way I could install a ladder for them to get in and out of the coup. I wanna install a roof but think I will need to get it slanted somehow. There are two roosts ( I think…) that are 30 in wide.
Fairly spacious! However, from this pic, it looks like there is water damage inside. Before you go too far improving, be sure the main frame of coop is sturdy, not rotten. Then check roof carefully (will you need to just reshingle?, totally new roof?, or just patch??) A good, non-leaking roof will be critical.
Based on the 60-70 sq. feet of coop, and the approx. 100 sq feet of run, it should comfortably hold a dozen full sized chickens or so (not sure how many nest boxes there were?). Remember the points in the article, though. . .depends on chicken temperments, your management style, whether they will free range at all, and also, though not mentioned explicitly, whether or not you have a variety of roosts
both inside and out so if there is a squabble, a hen has a place to go to get away. I would start with fewer, though, as it is easier to add later than to subtract when you get attached. This will also give you a chance to see what works for you, what you like/don't like...without everything being maxed out. And without you nor your hens being stressed.
Plus, after a couple of years, their laying drops off, and you will want to add more hens if you are raising them for eggs. If you start with say, 6 hens, you will have plenty of space to add more in a year or two to keep the eggs flowing without having to rehome or process or build additions! (Trust me, I've been there on this one

.) Decide what will
work for you.
