Ok so awhile back I hatched eggs from some barred rock hens and a big beautiful rooster that I don't know what breed ( I posted him before trying to find out but no luck). He was black with green tail feathers with a purple sheen on his feathers. Anyway, I hatched 11 out of 21 eggs (2 EEs 6BR and 3 solid black chicks). Unfortunately I lost a BR and a black chick. Now the barred rocks a a month shy of maturing and from what I understand of chicken genetics is that if my roo is not a BR then my chicks are probably roos , but out of the 5 two of them has a fairly pale combs(compared to the others that act and look like roos). Could this mean that its possible I have 2 hens rather than roos or I'd it a nutritional type thing that they are lacking? What do you think?
