Welcome to BYC. Glad you decided to join our flock. The other members are correct. No rooster breed on the planet is going to be able to fight off the larger and more dangerous predators such as large dogs, coyotes, wolves, bobcats, raccoons, eagles, etc. The rooster will just as likely fall prey to them as the hens. If you are free ranging your flock in an area with these kind of predators, you are going to lose some of your flock. It's up to you of course to determine whether or not those losses are acceptable. If not, then you need to keep you flock in an enclosed coop/run that's built like Fort Knox. Be sure and use hardware cloth rather than chicken wire and if you have coons in your area, make sure that you use a padlock or at least a double action latch on your coop door as coons can easily figure out how to open a single action latch. Please feel free to ask any questions you may have. We are here to help in any way we can. Cheers.
