My Buff Orpington (front) and a Red Sex Link (behind) at the same age as yours. Hope that's helpful to you. Don't you hate it when you think you're buying something and it turns out to be something totally different? When you're new to the chicken world most yellow chicks look alike! The Red Sex Links have a little buff on their backs as chicks and the Buffs (at least the ones I got) were soft, all-over yellow.
