I've got a light in my coop that comes on around 4, turns off at 7, to give the hens a little extra light as we're far enough north that we're already under 14 hours of sunlight a day. This morning, one of my hens was screaming the egg song at the top of her lungs....at 5:30 am. She never even laid an egg, actually. She just sang and sang and sang. I got up, went out, turned off the light, then petted her for a bit to try to get her out of that state of perseveration....and went back to bed. But she went back to singing. I could put the light on after dark, but then she sings the egg song well after dark. My coop is actually closer to my neighbors' houses than it is to mine, due to the necessity of the lay of my yard (that was the only flat spot). I do NOT want to turn the neighbors against me. What I can hear through my window is only the -GAWK! of buk buk buk bu-GAWK, and I hope that's all they can hear also. I don't think it's worse than the local crows - but it's loud and irritating....and unlike crows, which you can't do anything about, these are domestic critters. Can I retrofit my coop to be better soundproofed? If so, what can I put up on the outside? It's just plywood, and it does muffle the sound to some degree. I want to muffle it better.
