My old rooster, a Blue Andalusian/ Black Jersey Giant was awesome at letting the flock know what was going on. My current rooster, an Ameracauna, has grown into the job to the point that I know his "hawk" warning from his "dog/coyote" warning. I've put four coyotes on the fence in the last 6 months- that is to say, I shot them and hung their carcasses on the fence at the back of the property as a warning to the pack. I've got a couple extra roosters that are shaping up to be good boys. I'm in central Texas; if that's convenient to you, you're welcome to pick one up. I'm just going to eat them anyway.
