I have a question on sex-links. I have been reading up on them lately because I am trying to hatch some for a friend. What I have read is that almost any roo (except barred) over barred hens (mine are Barred Rock) will give you sex-links. So DMRippy was nice enough to confirm that my EE roo (Columbian pattern, I think) over my BR would give me sex-links. Those eggs are in the bator now and I am anxiously awaiting that hatch.
The EASIEST way to think about sex links is this: ANY solid colored rooster Over ANY barred or barred gene hen Last summer, though, I hatched some BR eggs from the hens that are in with my SFH just to see what I would get. They came out looking very much like SFH, they weren't black and they didn't have spots on their heads even though they were both boys. Why didn't it work? Any ideas?
