I have 2 brahmas that I love and I wanting to add 2 silver laced wyndottes and 4 silkies to my flock. I let the two I have free range during the day only when I am home, I want to do the same with the silkies. I guess my question is are silkies at more of a risk of hawk attacks than large breeds? Would having a mix like this help keep my silkies safe? Still learning but loving my chickens!
