I've kept coturnix inside and they are dust generators. As
@Nabiki said, if you have any dust allergies, I can't recommend keeping them inside. Also, the males crow constantly, though less so if they have enough hens around (5 hens per rooster). If they're right outside your room, you'll probably hear them all night long. I had a bachelor pad with 6 roosters in it in a spare bedroom for a few months. Even with my bedroom door closed, I had to run a white noise generator to drown them out. If you can figure out a way to keep them outdoors, I highly recommend it. Once they're fully feathered, you really don't need electricity anywhere near their cage unless you plan to provide extra lighting to promote egg laying year round (they need about 14 hours of light per day to lay consistently). As long as they have adequate shelter and can keep dry and out of the wind, there's rarely a need for supplemental heat. Though Michigan winters are harder than the ones we have in Texas.
@Nabiki is in Oregon and keeps her coturnix in a greenhouse.
