It is nice housing for your flock.
Here are some of my thoughts.
I do not see any ventilation. I do see windows, but unless they are opened, and protected from predators breaking in, they are just providing natural daylight. (which is a GOOD THING.

)
I do see quite a few chickens there. They do all poop on the floor. Poop generates ammonia. Ammonia is one thing that small chicken lungs do not NEED. That is why continuous ventilation is SOOOOOOO important.
You don't have your location in your profile, or posting. I understand that you are New Here.

Without your general location, It is difficult to offer advice. Especially with weather topics, and predator topics.
And finally do ask whatever questions you may have. There is a whole community of knowledgeable peeps that can advise you on correct action to take.
WISHING YOU BEST,,,,,,,,,,,,,,,,,,,,,and
