Dark Brahma Roo over Barred Plymouth Rock?

[MysticOutcast]

I read somewhere that this mix creates black sex links, but haven’t been able to find any other information about them. I’ve started hatching eggs recently from my flock and the third “bsl” hatched this morning, they’ve all come out black with patterns and feathered legs, however this third one doesn’t have a white spot on its head. I had assumed from what information I’ve been able to find the the bsl Roos will have white patterns and the hens will be completely black, but 3 roosters of this specific breed in a row is making me doubt, plus I really want hens as we are not keeping any roosters. So my question is does the dark brahma roo over barred rock mix 100% create a sex link? And if so do you determine the gender from whether or not it has white patterns or is it the white spot on their head specifically that marks them as a roo?

Yes, it will. At hatch the males will have a light dot on their head. When they grow out the males will be barred, which is the stripey pattern you see in your barred Plymouth rock. The females will not be barred.

So the females will still have white on them as chicks just no white dot on their head?

I agree with Emma. Just about any non-barred rooster over a barred hen will produce sex links. A barred rock hen has only one copy of the barring gene, and she invariably passes it on only to male offspring only when mated with a non-barred male.

Yes. The third chick is a female, then.

Yes they can.

Just wanted to clarify for anyone reading this. Sex links can be created using barred hens and solid roos. With this combination only males will inherit barring. If the father is barred, chicks of either sex can end up barred. As a chick, a white spot on the head indicates barring.

but 3 roosters of this specific breed in a row is making me doubt,

Dark Brahma roosters aren't solid dark colored on their heads at all.. I agree and don't think this specific cross will work well for sex linked chicks.

Thank you for sharing!

White spots on the head as chicks indicate barring. Dark brahmas are not barred, and do not have white spots on their head as chicks.
