What are Sex Links mixed with?

[Donnigan]

I know they're a cross between a couple different breeds but i don't know which ones!
Also how many varieties of Sex Links are there? I have Red Sex Links and have heard of Black and Amber. And where can i get different varieties? Thanks

I believe there are really only two varieties Black and Red sex links but they are known by many other names (Black stars, Golden sex links, Red stars, Golden comet, Red shaver, ISA brown ect.). Black sex links I believe are crossed with a red rooster (Rhode Island red, New Hampshire Red) and a Barred Rock mother. A Red sex link I think is crossed again with a red rooster and a white hen (I think you can also use a Delaware or Silver Laced Wyandotte). Now I'm not an expert and I hope someone corrects me if I'm wrong.
