Wow!!! 22 chickens in your house?!?! I am impressed. I can barely handle one convalescing chicken in my basement who gets cleaned everyday. You have some... dedication?
Still, it's not healthy for any of you. Chickens and humans can pass diseases and parasites to one another in such close proximity. That many chickens need space to roam, ground to scratch at, good ventilation. I recommend building a very tough coop and then adding a run completely enclosed in hardware cloth. You don't have to lose chickens to predation. There are great plans everywhere for strong coops. There are also pre-made coops at most of your local agricultural stores. (I have to say that the ones I've seen are lovely, but usually pretty pricey.)
It's nice you care so much about your birds, but they really do best if they are in their natural habitat. Good luck!
