I don't how I missed you you already have hens, babies are nothing compared to them. I brood in my basement until they are feathered and hardly hear a peep. You're good! I was so worried when I got roosters (even though I'm allowed, it's rural here too) but most of my neighbors came over...
Grown chickens are noisy, even hens. I have a few that announce to the entire neighborhood everytime they lay an egg. Have you checked you're allowed to have them where you are?
Just noisy in the incubator until you take them out. Once they are comfortable with a heating plate or lamp they're pretty quiet... loud chirps mean something is wrong... usually too cold. I just couldn't imagine sleeping with them in my room while hatching.
I know my chicks took about 2 full days for everyone to hatch and dry up to be moved to the brooder and they were REALLY NOISY! Be prepared for a few nights of no sleep if you have them in your room lol. I had mine in a large closet/office space downstairs and I heard them chirping upstairs in...
