We have 3 Speckled Sussex babies that were born at Christmas. Two of them were born with the same black feet that our Silkie Mix babies have. However, the third (who struggled to be born at all when he/she couldn't get through the shell of the egg without help), has pink/orange feet and a large cone. I know my other Sussex hens all have large cones, but I simply cannot tell if these last 3 are male or female. Thoughts?
