Not sure it's about the leg color.....more about the quacking and the peeping. Boys just peep and girls quack. Katsdar, when they are a month old, their voices change. They will all peep like chicks until after a month old. Jack, when I was there, you had lots of girls. Wish I had gotten more!And I think all my K-C's are drakes. They've all got yellow feet now. Haven't grabbed them to make them scream yet.
