Sexlink roo with a barred rock hen?

[Littlepetal]

hi all,
I bought some fertile eggs from a lady who thought her roo may have been a sexlink (she wasn't 100% sure). The roo was in with barred rock hens. What would the chicks look like (trying to pick gender)? They are now three weeks and I have gone from 1 roo, 1 pullet and an Idk, to maybe 3roos. If he was pure barred rock I think I have Roos.

If the cock bird was indeed sex-linked, then it's my understanding that the off-spring will not be sex-linked. Maybe give it another 3 weeks and then post pics on this forum -
What Breed Or Gender is This?

Oh, and welcome to BYC - thanks for joining us.

Ok great, this guessing is doing my head in

not sure what the father was, but assuming it was not a stripped chicken... the mother will only pass the barring on to her male offspring. any day old that has a yellow/white spot on it's head should be a boy.

as long as the father wasn't stripped.

ETA: Striped not stripped lol

If dad is a sexlink, and he were bred to a nonbarred bird, you would get 50% barred and 50% unbarred chicks, both genders, as dad has only 1 barring gene to pass along.

If he is bred to a Barred Rock barred hen, who likewise carries 1 barring gene, then you will get 25% double barred males, 25% single barred males, 25% single barred females, and 25% nonbarred females.

So any pure black chick will be female, but you have a 1 in 4 chance of getting that.

A smaller head dot, slightly darker bird will be half and half, male or female.

Any bird with a large head dot and wider, heavier barring will be male....but often hard to distinguish from the single barred male unless side by side.

So unless you lucked out with a pure black female, you've got barring both genders to sort out....some single both genders, but only males double barred.

Thanks! No pure black chicks unfortunately (can't keep Roos). Will just have to wait a few more weeks
