Hello. Just a quick question. Instead of vent sexing my chicks, I would like to know how to make a sex link. I have Black Australorps, Production Reds, White Leghorns. I know the ee's or red sex links will not do anything so don't worry about those. Just tell me what rooster of what breed and what hen of what breed I need to get to get a sex link. Or just tell me what breed I need to buy to go with some of the chickens I already have. Thank you for your help.
