Hi everyone! These are two day old chicks from my barnvelder rooster and mostly barnvelder hens (3 are from an Easter egger and should lay olive eggs, and one is obviously leghorn). I also hatched what I hoped to be barred rocks, because I wanted to try the sex link thing. If so, I guess I got lucky and got four pullets, since they don't have a white head spot. But now I am wondering if I may have gotten some of my Australorp eggs by mistake. What is your opinion on the blacks? The all look the same as the little one on the fence post. Aussies or BR pullets (same barnvelder roo for all the hens). Can I tell the gender if they are from the Aussies?
