You have 3 sq ft/bird and minimum recommended is 4 sq ft/bird. Unless they are guineas or banties, they are overcrowded. It is paramount that you have really super great ventilation, big-time with so many in such a small place.
I use deep litter method over linoleum flooring. It is 90% grass clippings. i only have to change it once a year. Reason is I have 24" wide poop planks full length under roosts that I scrape daily.
This is accompanied by windows open first thing in AM regardless of temperature. My chooks stay out all day unless it is just pouring rain, and even then they will congregate underneath the tallest part of the coop outside. So I have no problems with poop at all. Worst place for me is their stoop outside which I sweep daily with an old broom that stays in coop. You could look into poop planks and deep litter for your operation and both will help.
Since you have so many chooks, I thought of ventilation too. What is your full-time ventilation size? I have 24 in an 8x16 coop and I have 6 sq ft of full-time ventilation above the 8 ft level and 4 large windows on top of that which add 40 more sq ft to my ventilation in warm weather. So I have 1 sq ft ventilation full time for every 4 birds even in winter with all windows closed.
My vents are on upper part of each of two gables, one turbine vent, and continuous soffit vents 18 ft long X 1 inch wide, both front and back soffits. By my reckoning, you should have 25 sq ft ventilation that is full time for optimal health. I am only including this because of the size of your flock, and the impact on you should they develop lung problems being such a large home flock.
