Can the saddle be seen in a chick? Can the cape?

Typically, male characteristics do not become apparent until the birds are several weeks to several months of age as they are determined by hormones. Distinctively male type saddle feathers would not become evident until after the juvenile molt, after about 10 weeks of age, when the first adult feathers grow under the influenced of increased concentrations of male hormones.
Color or feather sexing in chicks is strictly genetic, generally determined by a single gene.
