Welcome to BYC. Glad you decided to join our flock. Because Isa Browns are hybrids (Red Sex Links) utilizing a white feathered hen, you are not guaranteed to have sex link chicks. The following is a direct quote from our section on "sex linked chickens" at https://www.backyardchickens.com/a/...beginners-what-they-are-and-how-to-breed-them, specifically with regard to breeding Black Sex Links which use the Barred hen. " Problems with breeding this sex link: you should use heritage chickens in your parent lines, most hatchery grade chickens have crosses that mess up the sex link properties. In your red rooster parent, look for red earlobes and dark feather coloring free from any white spots and light colored shafting (which Isa Browns have). Your hen should show no signs of red feathers, and carry a descent quality barred pattern. Sex link characteristics will not carry through if you try to breed the offspring." If you want guaranteed Black Sex Links, you need to get a pure red gene rooster (RIR, NHR, or Production Red). Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck with your flock.
and Welcome To BYC!
