I recently heard that sex links are created with a BO Roo and Barred Rock or Silver Laced Wyandotte. We have one hen of each breed and now I'm trying to figure out what I have? I can definitely see barring in some of the chicks wings but I am curious if the sex link information I saw is true? If so does anyone know what mine should look like?
Yes, you should have some sexlinks.
Predictions for chick colors from each hen:
Sexlinks:
Barred Rock mother produces sex linked chicks. Both genders have a lot of black, and may show various amounts of gold or red. Sons have white barring, daughters do not.
Silver Laced Wyandotte mother. Assuming she has a rose comb, any chicks with rose combs must come from her. Her chicks will be sexlinks too. Sons will have a black-and-white pattern (may show some gold or red in their shoulders as they get older.) Daughters will have a black-and-gold pattern. Some Wyandottes have single combs, or carry the recessive gene for single combs, and if your hen has this gene it will be harder to recognize her chicks (daughters may look like the chicks from the New Hampshire or the Golden Comet, sons may resemble chicks from the White Leghorn although the black will probably be arranged differently.)
Not Sexlinks:
White Leghorn's chicks should be most white, but may have some black patches in places.
Buff Orpington hen produces purebred Buff Orpington chicks, of course.
New Hampshire Red will probably produce chicks that are colored halfway between her color and the Buff Orpington rooster's color. I would expect some black showing in the tail, and some shade of red/gold.
Golden Comet may produce chicks that match the ones from the New Hampshire Red (including black tail), or may produce chicks with white tail & markings like herself. (Reason: Golden Comets are a hybrid.)
