Help me sex my chicks!

[Welshies]

I think a chicken that has a rose comb can also carry the gene for recessive pea comb. I think rose comb is its own gene, because I know I've read that chickens that are homozygous for rose comb can actually have reduced fertility. I think walnut comb is the one that is a combination of dominant pea and dominant rose.

It's actually good news for you if your rooster is not barred, because that means you will be able to identify a lot of the cockerels right at hatch. They will have a white spot on their heads. As long as their down is dark enough to make it out, you'll know they're cockerels from the get-go.

Oh okay... Makes sense. This is actually sort of cool. What about the chicks from the black hen?

Those you'd just have to sex the old fashioned wait and see way

Yes but one barred is a pullet I honestly think. Mind you I am stubborn sorry for the pigheadedness.
Here's a group picture. I really appreciate the input but I don't understand how that can work. I've only thought of 2 as cockerels, one black and one barred. Hard to wrap my head around.View attachment 1223957

But many that looked like pullets turned out to be cockerels all the time... you wouldn't be the first to swear a slow developing cockerel was a pullet, I have had many myself I thought were pullets prove me wrong...

But the barring gene is proven science... and this is how many a hatchery can guarantee pullets at hatch... black sex-links are made from barred hens and non-barred roosters...

Thanks for the pix. I see at least two with a very clear white dot.

Rose comb is its own gene...and is dominant

pea is its own gene. .. and is dominant

pea and rose together are walnut.

Also as far as I know, there is no such thing as incomplete barring. A chicken either has one copy of the gene, two copies possibly if it is male and got a copy from each parent, or no barring at all. So, single barred, double barred, or not barred.

completely correct...

but....

there are modifiers that can make some of the barring fade out.

I knew there was a comb with pea in it!

I stand corrected, rose comb is not pea and cushion comb... but pea comb is in other small combs...

And barring is stil sex-linked...

Genetic impossibility for any of the barred chicks to be pullets. A barred hen can only pass that gene to her male offspring. It can not be passed female to female.
Chicks from the black hen can not be sexed by coloring. You'll have to wait and see.
Could you be off on the age at all? They seem to be closer to 5 or 6 weeks then 8 or 9. Might be coccidiosis. They look like they are either chilled or sick.

yes, barring is sex-linked. A great way to know sex from an early age.

Hmmm... but, all my chicks are either black or barred. The barred ones would be males, right? But what about if they came from the black hen? Or would the black hen produce black chicks because black is dominant.
Any pullets coming from the barred hen would be black, due to sex linked right?
