These chicks were purchased from a local feed store which purchased them from Ideal Poultry in TX which uses a RIR rooster over a barred Plymouth Rock hen. They were sold as black sex link pullets. I haven't raised many black sex links, but I have raised some, and I have looked at every photo I can find. These chicks, probably 10 days old or so, look nothing like anything I can find. Also, one is already beginning to look and act very Rooish, long neck, much larger feet than the other, more pointed facial features, but no yellow spot on its head. I have emailed Ideal, but in the meantime, has anybody had a black sex link pullet that appeared to be barring on the wings at such an early stage? All of my others have been black with gold or red developing later beginning around the neck. In my case, the breed isn't much of an issue, but the sex sure is. Thanks!
