Only works with hens with pink and yellow legs I believe. I am no expert but I am looking into this as well with my flock. The female chicks will have dark skin and the male chicks will have light skin.😊
Makes perfect sense then as silkie crosses often have 5 toes. Do you know what breed or leg coloring that the mother has? If you do, you may be able to determine what gender the chicks are.😊
