I have 4 girls and 5 boys. I'm not keeping all of the Roos....but I am hoping to get more hens/ attempt to hatch out some eggs. My Olive Egger seems to be my best layer at this point. Big green egg almost every day. The eggs seem to be fertile from one of my Roos. All of my Roos are silkies, one being a Silkie Cross. My non Silkie chickens seem to be the best suited for our area. The silkies are the only ones that seem bothered at all by the cold (small amount of frostbite). I want dual purpose birds that are cold hardy. What would the OE crossed with a Silkie (or the Silkie cross) be like? Or am I better off getting rid of the silkies altogether and trying for another breed of Roo? My other 3 hens are a Silkie, a black star and a barred rock.
