Chickens aren't very noisy if kept happy. As long as you spoil them and give them enough space outside as well as roosting space inside, and keep their area cleaned up and fed regularly, they don't tend to make a whole lot of noise.

They do work in schedules. If you're an hour late to feed (assuming you don't free feed), they'll let everyone know.

Just my .02.
