I have a Serama roo outside, and he's not too loud. I have Old English Game Bantams, and he's not quite as shrill as they are, but close, he's young, they are young, and they are all distinctly different! I hear Roo #1, then #2, and I wait to hear Roo #3, then I know all is okay.... My bedroom is 10-15' away, and I hear them, they wake me up, but I guess I"m not bothered by the noise. I"m an early riser anyways. I had him inside for a while, and inside a tiny house, it was a bit much. I guess it depends on the proximity of the coops. They are nothing like a large rooster, and unless you have really sensitive neighbors, or if roosters are illegal, it shouldn't be a problem. Other people on this forum have made indoor rooster boxes for them, and it works well, even in illegal areas.
