Are these invented ??would they work ?? I was thinking i really want to breed chickens but i cant becasue i cant have roosters . But then i thought Could a rooster wear a muzzle to stop it from crowing ?? Because my chiahuhua has a muzzle for when he goes to the vet (he get a little nippy) and he can eat and drink and lick but he cant bark !! So could a rooster muzzle be made so that he can eat and drink and mate fine but not COCKADOODLEDOO every 3 minutes ?? Maybe ...Maybe Not........?
