Oh, I had this problem too. Mine was a Cockoo Maran. She was so loud. She started every day at 6:30am. She also got her sisters going. I would run out every morning to try to quiet them. I had 5 hens and 3 were so loud I moved them into the garage till about 9am. I am in a suburban area and I am not zoned for chickens so having loud girls was not fun. I finally had to get rid of the offenders. I did the craigslist thing and has my choice of homes for them. Now I have my two quiet girls and life is so much better.
