One of the chicks must be an Araucana.  It has fluffy cheeks and green legs.  The other one has green legs but lacks the feathery cheeks.  I bought six chicks altogether, 2 silver-laced wyandottes and two red stars with my Brahmas-turned Araucanas.  One of the red stars is half the size of her flock sisters.  She's eating, drinking and seems healthy.  I'm wondering if she is a bantam red star (if one exists).  I guess the help at the feed store needs some lessons in identifying their chicks.  Have you ever heard of a bantam red star?
