BO's and BR's chickens

[Mraya]

I hope I am posting this in the correct area.

I have BO roo and a BR roo also BO and BR hens but I do not separate them. I am incubating eggs now. When the eggs hatch is it safe to say that all the yellow or light colored chicks will be BO's and all the black or black with head spots will be either BR's or Black sex Link?

Is it safe to say that all the yellow or light colored chicks will be BO's

Yes, the BR hen or rooster is based on black and the down from any of them in any cross with a BO will be black. So by default any yellow chicks are BO's.

all the black or black with head spots will be either BR's or Black sex Link

No. To get black sex links the hen has to have barring and the rooster cannot have barring. Your BR rooster has barring and will pass that down to all his offspring, male and female. So any black chick with a head spot might be a black sex link male or it could be a pure BR but either male of female. Any solid black chick without a head spot will be a black sex link pullet.

Thank you I was starting to confuse myself
