I'm in a very similar situation such as yourself, and you have my sympathies. Even though I did research in advance, and got really quiet breeds, they sometimes cause a ruckus.
When they are in the coop, the noise is minimal, so waking up at about 7:30 and letting them out works. You may want to add insulation to the walls of your coop, and maybe install blackout curtains so they can't see the sunrise and wake up. Just make sure you have adequate ventillation.
Also, once they are out in the run, you can give them something called Flock Bloc, which is a huge hunk of chicken treats. THey spend time pecking at it and entertaining themselves instead of screaming for treats.
Just a few suggestions, good luck and don't forget that fresh eggs for your neighbors goes a long way!
