I find sexing day old SG Dorking pretty easy. I will send you a pdf that helped me when I started and found it to be spot on.
Have fun, we love raising them.

Kim, great pictures of your dorkings from February. I waited until the end of April to hatch some of our dorking chicks because it had been so cold up here. I ended up culling the rooster after the hatch because he threw three 4 toed chicks and he was so darn mean to us. I was super excited...
The first ones I got from the hatchery in July started right at 5 months. I hatched some out last October and they did not start laying until late March this spring.
