So, a Sex-Link is a type of chicken where you can tell the gender at birth. The offspring usually inherit the genes from the opposite sex parent. Red (or black) cock x Barred hen = Black Sex-Link, then a Red cock x Silver factor hen = Red Sex-Link. I get that, but I see a lot of questions where people ask if their cross will be sex-linked. So, my question is, how can you tell if a cross is sex-linked (besides basing it off other crosses), and what are some other crosses that make a chicken sex-linked?
