I've seen rooster collars on roosters, and many people claim they are great in reducing the noise level. I am wondering if they work on HENS, has anyone ever tried this? I have 3 extreamly loud hens, it's to the point where I might have to get rid of them if I can't quiet them down. They sing the egg song constantly, all day long, all 3 of them, even when they are not laying. They are almost as bad as a rooster. They chatter and bock all day too. I've had them since they were chicks and they are a over a year old now. I'm thinking of making my own out of Velcro, I've seen this done on roosters. Any thoughts?
