Is there any dual purpose breed that is better at foraging in a heavily wooded area? I am not sure that I am comfortable with this idea or not, but we are planning on moving to a new property that is very secluded and only has a few open areas. I currently have my few chickens locked down like Fort Knox but want to expande my flock. Lots of coyotes and hawks in the area. Will a couple of great pyrenees help with guarding the flock?
