Thanks everyone, you guys are great! The racket is usually in the morning, but not at sunrise. It is not the "cock a doodle doo" sound, but it is much more than the purring the ladies make. The other day, around bed time for the chickens, 1 went towards the hen house first and made a loud noise, which brought the others running to go inside. I am thinking I just have a dominate hen like everyone has suggested. I am getting eggs from 2 or 3 hens now, so a couple of more weeks I should be %100 percent confident there are no roo's in the mix.
Thanks again
