Folks, the whole point of silver/gold sex-link crosses like Red-stars, Comets or whatever is that you can tell the sexes apart by their color, even at hatch time. They have sex-linked genes for color and that's why they're called "sex-links." Thus, the males are usually white, and the females at least mostly red. The only way these are sex-links, that is ISA Browns, Comets, etc. is if they're all female. They're not. So, they're not sex-links. But, they are probably sex-links back-crossed to a RIR.
