I am not sure how to search for this, so if a good thread already exists, I'm happy to read it. I want to use my white production leghorns, in some combination, to produce a sexlink (the goal is a layer with some production leghorn in it). I understand basic "sexlinking" at a high level (male 2 copies/female 1 copy) and I also am aware (and have found by experience) that simply crossing a white leghorn often (in my case, always) produces all-white offspring. I'm aware that this is how the ISA Brown and other proprietary crosses are made, where the terminal cross is the 3rd generation. Can I produce a parent from crossing white production leghorn with something, and using that resulting generation in a sex-link cross? If so, can someone help me with: Understanding what to do Choosing a good combination I've got Production White Leghorns, Light Brown Leghorns, Dark Brown Leghorns, Rhode Island Reds, New Hampshires, Barred Rocks, White Rocks, Buff Orpingtons, Silver Laced Wyandotte (hens only), American Bresse (hen only), Black Copper Marans, Ameraucanas, Dark Cornish.
