Thanks to Keara for the link Hawaiian 'Chicken Eggspert' explains how to stop your rooster from crowing at the bottom of this article. http://www.hawaiinewsnow.com/Global/story.asp?s=6273414 Here are the options in summary HOW TO KEEP YOUR ROOSTERS QUIET: -Black out the bird's cage at night -Put a muzzle and collar on the bird -Put a hood or a sock with a hole over the bird's head, and cut out space for the beak and nose -Soundproof your pens -Lower the ceiling of the coop after the bird gets on his perch for the night Here are my initial thoughts on the quiet rooster tips #1 - Our cockerels crow in the middle of the night #2 - What kind of muzzle would stop a rooster crowing, while allowing him to eat, drink & breathe? #3 - Are the beak and nose in a different place on Hawaiian chickens, doesn't a hole for one kinda provide a hole for the other? #4 - I totally misread the last word and thought 'what good would that do ?', then I read it again properly and thought 'How?'. ( 'How?' would be appropriate to my original misinterpretation as well ). #5 - What? Has this person had Xzibit 'Pimp their coop' and they have hydraulic lifters in the roof of their coop, and gleaming gold alloys on their chicken tractors I know only one way to stop a rooster crowing, involving a machete, a block of wood and a barbeque.
