I came nab my standard breed roos but my 2 little Dutch banties are so fast I can't reliably catch them. When I let them out to free range sometimes I want everyone back inthere runs before dark and the roos refuse to go to their coop. They try to go in with the standard hens which sets off the resident roos. I tried a net, which worked just once before they learned to recognize it and stay out of reach. Any secrets to catching these zippy little terrorists??
