The answer to your Noisy rooster and angry neighbors!
 
Made of high-quality nylon and velcro, with a hook and loop design and adjustable size. 
 
Rooster collars work by diminishing the force behind roosters' crows. Reserves of air from air sacs (in addition to their lungs) are expelled all at once when they crow. It tends to limit the force of the air and makes the crow quieter.
 
The collar does not guaranteed to fully stop your rooster crowing. It is designed to significantly reduce the volume and frequency of crowing. Results may vary from rooster to rooster, and are dependent on the person doing the fitting.
