Sex- linked Information

[curious chickee]

So, I have managed to hatch out 15 chicks (so far) from my Buff Orpington rooster over Barred Rock hens. I got chicks with very yellow faces and heads, and then some that appear mostly black, but can see a darker red face. I assume the yellow are cockerels? What's throwing me off is some of the blacker ones look like they might have some white feathers on top of their heads... Help?

Buff rooster over barred hen,orange face chicks pullets & white face chicks cockerel. I did this cross many times

I have one that's all black with just the tiniest snip of yellow on top of its head, would that one be male too?

I want to make sex-linked chickens that are TOTALLY awesome and I want to use barred/cuckoo hens to do it. Please list all varieties of NON black breeds that are barred or cuckoo so I have an idea of what's out there. Thank you all very much for your help

The terms "barred" and "cuckoo" refer to a color that is EB (extended black), plus Barred. For non-black colors that have the gene for Barred, you should look for a color called "Crele". Crele is wild-type (also called partridge or black breasted red in some breeds) with the addition of Barred. Crele results in chicks that are (usually) autosexing, like the well-known Legbars, Rhodebars, Welbars, and Bielefelders. "Sex linked", at least in the context of this thread about sexing chicks at hatch, comes in several types. You are obviously referring to the "black sexlink" because that is where the barred gene comes into play. You can make black sex-links with Crele hens, just as you can with barred/cuckoo, but the cock must have extended black to "override" the wild-type chick down and make the chicks sexable by the white head spot. If you use a crele hen and a BB Red roo, you will have trouble sexing the chicks by their head spot. To sex the chicks accurately, you must use a crele roo (autosexing chick down) or black roo (black sexlink).

Thank you for your criticism.
I said barred/cuckoo because both cuckoo and barring are caused by the barring gene regardless of the genes present at the E locus.

It sounds you are telling me that it is impossible to breed chicks that are identifiable from hatch and that will grow up to be striped like a barred rock (except with color where the black is)?? harrumph look at this picture. Moving forward now.

So, other than Legbar, Rhodbar, Wellbar, Bielfelder, are there any other non black chicken breeds that have the barring gene.

I didn't intend that to sound critical, just trying to explain term as I understand them. To answer your other question, white chickens can have the barring gene in their genotype, but they don't express it in their phenotype because barring adds white and if you start with all white, you won't see the effect of barring. Depending on your interpretation of "non-black", you could include EB modifiers, like blue (BBS and Lavender). There are colors like lavender cuckoo and lemon cuckoo. I consider blues to be black with modifiers, but would they meet your criteria?

I didn't see it as critical, I have enjoyed your posts and have found them very informational. Thank you!

@dheltzel I may have overreacted. sorry about that

Thank you for the suggestions. I do appreciate it.

I don't want to make anyone go away or give up by my wording of things. Genetic understanding is not always easy for me and I want to make what I've learned accessible to anyone. I still have very poor understanding of some traits, so I don't want to come across as a "know it all". I do enjoy helping people whenever I can.

The yellow/white dot on head is a sign of barring (male). Girls will not have dots on their head. Their face is orange from the buff leakage. The males could look mostly black any white/yellow around the face is a male indicator.
