Can I

[WindingRoad]

build a loft in a taller coop and increase my flock size by half. For example. Can I have a 10x10 coop. 100 sq ft. With 25 birds on the first floor and another 12 birds in the loft. I would only build the loft about 1/2 the size of the foot print. But I could put nest boxes, and roosts up there for bedtime. ETC.

You're figuring base minimum (100sq ft for 25birds), just understand BIGGER the better. What about their run? Or are you expecting to free range daily, weather permitting? If you're putting the nest boxes & roost upstairs, you're taking space away from your footprint. Also depends on the breeds you have/keepin. It may work to "increase" your bird capacity but be prepared for possible squabbles & having to enlarge your space

Chicken Math is very difficult to control. I have a 8 x 12 x 7 Chicken House (coop/run combo) giving me a 96sq ft space & mine are confined. I allowing myself no more than 6 (4sqft/coop & 10sq ft/run = 14sq ft per), however find that 4BO is all I'm comfortable keeping. I've also had 5 Wyandottes fit comfortable and no squabbles. I want my chickens happy & comfortable, avoiding squabbles & keeping egg production up.

Thanks for your info. Just curious more than anything.

Yes, I think you could. I think cubic footage is definitely a factor to consider, not just square footage. You still need enough run space as has been mentioned, or perhaps not if you are free ranging.
I made a double decker arrangement for raising chicks in the coop. I made their enclosure under a roost. (top of enclosure is a wide poop board)
When the chicks were bigger, I removed the dividers and they continued to roost on the lower story roost for a few months.
