My White Bresse rooster screams. It's a really deep, long crow. The loudest of all my roosters.I love knowing who is who. I do have two that I can't really always tell apart. The Toppy and the Hulsey are both ear splitting crowers, and will crow on top of one another alot. I have a LCO that is starting to crow and has a similar crow to the rooster that went to COF. Deep and long. Those and the OEGB are my favorite to listen to. I like the little squeaks at the end of the tiny guys crows.
