We (surprise ) ended up with a double flock (brother backed out last minute, leaving us with his half of the purchased 24 - and how can you say no to those precious fuzzy babes?). The coop walls had already been framed. Coop is 8X8, but to accomidate roost space we raised the roof to 11 ft. tall (we're gonna have to call this place the 'Chick-N High Rise'!) so we can have roost space for one and all, "laddering" all the way up. We're installing 18 nest boxes (will have perches). I'm thinkin' it's gonna be a little tight in there for 24 chickens in 64 sq. ft. of floor space. What problems will this pose? Or will the adequate roost space make up for the tight floor space? Also, the run is going to be 8X32, 6' High. That leaves approx. 10 ft. per chicken, and they will have access to the run 24/7. Advice: do you think this will work, or should I consider adding an extension before the coop is completed?
