Review on 6 Pack Anti Crow Rooster Collar Upgrade - Noise Free Chicken Neckband for Preventing Screaming and Rooster Crowing - Nylon Neck Belt by Brandi Davis

These collars are Velcro straps with raw edges. I understand they must be uncomfortable for a cock, but the edges on them were so rough they cut into the feathers on the neck of my cock, leaving it with bloody, rough skin. That's even with the little finger space from his neck to his collar. The collar reduced the length and frequency of the crowing, and lowered the volume somewhat, but that didn't stop him from crowing. his crowing was still clearly audible to our "neighbor in nuances" whom we bought a collar to calm him down in the first place. Our tail ended up ripping it off the neck entirely, rendering the velcro fibers non-recyclable. He wore it for about two and a half weeks before he managed to take it off. On the plus side, they have beautiful colors, great customer service, and a return policy.
