I am not sure on the breeds of my chickens. I got them from a gal who ordered several hundred by mail and was getting rid of them. She said there were red leghorns, barred rock and speckled sussex. I don't think she was right. Also, can you tell if any of them are roosters? I keep hearing a few of them crow in the morning and I can't tell which ones are doing it. They never crow when you are looking. They are 9 weeks old. Thanks.. Ps thanks for the patience with another newbie.
