Looking at the chick pictures, I still think that Sivir is a Production Red, Kassie is a Red Sex Link, and Kayle (and Morgana too) are Dixie Rainbows (Pioneers) and they are all hens.
Welcome to BYC! Sivir looks like a Production Red hen, Kassie is a Red Sex Link hen, and Kayle may be a Dixie Rainbow (Pioneer) hen. I don't know what breed Morgana is (any other BYC members?).
