Sounds good then...still a tad small for the attached run, but considering they have plenty of space to free roam, I don't think they'll mind!
Very good point. It's hard to tell from the photo, but I don't see any vents other than those two windows. The windows are big but not placed in a way to move air from the bottom of the coop up out through the edges of the roof, to move ammonia out. Stagnating ammonia air can be deathly toxic to birds (and humans, too). Too little space and poor ventilation is common in the pre-built coops. Here's yet another good article on ventilation:
I posted the other ventilation i have in the above post.
