Use the standard 4 sqft per bird in the coop and 10 sqft per bird in the run. Those are general guidelines, and do not take into account individual situations. Be that as it may, if you use those guidelines as a "rule of thumb" you should be okay and have happy chooks.
These would be in the coop/run most of the time, not free-ranging?
The first coop has 12 sq ft indoors and about 62 sq ft of run. If you (sigh) go with the popular fad here of 4 sq ft apiece indoors and 8-10 outdoors, that would mean 3 chickens. (the run is big enough to give 6 chickens 10 sq ft apiece, BUT then they'd only have 2 sq ft apiece indoors and AFAIK Missouri gets enough prolonged yucky weather that I think you'd run into problems that way)
The second coop has 9 sq ft indoors and about 32 sq ft of run. Again if you (sigh) use the stocking densities that are popular on this forum, that would mean 2 chickens, or possibly a third if you squish them into only 3 sq ft apiece indoors.
Personally I wouldn't want to use either of the coops for anything other than maybe a crippled chicken who had to live permanently isolated, or if it were a teensy urban backyard where there simply *wasn't* more space available.
If they will free range most of the day every day, I would suggest not "wasting" too much money on a large run, but rather concentrate on a larger indoor coop. Anyhow it is real easy to add more/bigger run later if your needs change; whereas making the *coop* bigger is at best a giant pain in the butt.
The more indoor space they have, the better, from pretty much any perspective.
I'd suggest considering a small, simple shed design?
