I'm in Bonnieville, about 2 hours, I think, from Scottsville. It takes about 45 minutes to get to Glasgow, I forget how long to Scottsville from there.
Yeah, that's way too many birds to bring inside at night! I thought you just had one. The yard barn might help. If it's a smaller one, maybe you could hang old blankets or old carpet or something over the walls, that helps muffle sound a lot. I remember when I was a kid, they put huge panels on carpet on the walls of the choir practice room at school, to reduce the sound outside the room. I've read that cardboard heps, too. I haven't tried any of this, but it's what I've heard about. Or, what about putting them in cages in the yard barn, and put cardboard boxes (with air holes, of course) over the cages? I bet that would muffle them enough that they wouldn't disturb the neighbors, though it would be a real PITA to fetch in the roos every night and put them in the cages.
Mini-coop, movable pen type set up, just for the roos, with the coop part sound-muffled? Then you just have to close the coop when they go to roost at night, and let them out when it's late enough to avoid bugging the neighbors.
Any way you look at it, it sounds like a real PITA, to me. I'm so glad I live out in the sticks!
