I am new to raising chickens. We started out with 10 Dominique eggs and ended up with 8 chicks. Only 3 of them have very dark legs with light colored toes. Only one has light colored legs and toes. The others all have shadow colored legs. The one with light legs and toes is more gray and I assume it is a boy. One that has shadowed colored legs has a very distinct spot on its head. I have all the pictures on this website: cinemapremiere.com/chicks. I would greatly appreciate any help determining which ones are boys and girls since we only want to keep 3 hens and give the others away. I know it would be easier giving away hens than roosters.
