What breed of hen is this

[Sire12]

I've had her for a few years she's larger than average and lays quite a large egg compared to the others, she's pure black all over except for a bit of red on her neck, in these pics she is standing next to a blue Orpington for a size comparison

I thought black sex link when I first looked at it but I don't know now. Maybe someone else can help?

 

[Brahmachicken240]

Black sex link.

 

[Ted_Harrell]

Yes, Barred Rock crossed with some one of a list of breeds

 

[Ted_Harrell]

She lays light brown eggs right?

 

[Sire12]

She lays light brown eggs right?

Yeah after looking it up that's probably what she is, I'm going to hatch eggs of hers crossed with a brahma soon would I be able to gender the chicks then if she's a sex link?

 

[Ted_Harrell]

No, only her generation, not subsequent ones.

 

[chrissynemetz]

I agree, she's a black sex link.

Back sex link....
and no, She's a sex link, only in her generation (as stated above) because the combination of her red father (probably a production red or a Rhode Island red) to a barred mother (probably a barred rock) creates one generation of offspring that can be instantly sexed at hatch. Her brothers all bore a white spot on the back of their head indicating that they had the barring gene from their mother. She didn't receive it, and wouldn't be able to, because she's female. If you breed a sex link to another sex link, you will not have chicks that are sexable at hatch. It has to do with the genetics of the barring gene. Mothers can only pass it on to their sons.
