Sophie is a pullet,the "saddle feathers" that you are talking about are just to longer feathers that usually appears on hens.

The crow you might have heard could be a hen's bawk, some calls will sound similar to a roosters, when a hen's lost, spots danger, or is laying an eggs they will make long baawwwk-bawwk-bawk-bak-bak noises that can be loud. In some cases when a flock does not contain a rooster one hen will take the roosters role which includes crowing, most of the time these masculine hens will grow spurs and have more rooster-like characteristics, they might also stop laying.
