Sex- linked Information

That is a cockerel, and most certainly cannot be a Black Sex Link. He's a regular mixed breed.

Ok thanks! I wasn't sure the father is a RIR and the mother could be red sex link, RIW, barred rock, black sex link.

The mother was very likely the black sex link, none of the others have the genetics to produce a cockerel like that. Out of those possibilities, only the Barred Rock female should produce sex linked offspring. Although... I do wonder about the Rhode Island Whites - I'm not sure if hatchery Rhode Island Whites are silver or dominant white based. If they are silver based, then they could produce red sex links. If they're dom white, they'll just throw all white chicks.

It's funny you mention that in another forum I was asking about other chickens that appear to be RIW hens crossed with RIR Rooster they look like this there's four that are identical

Looks like a pure Delaware to me. It's definitely a cockerel. I don't see how it could be an RIR X RIW cross in any scenario - if the RIWs were silver based, then you'd get either red sex links (red females with white leakage, white females with red leakage) or 100% hetero silver chicks (all offspring white with red leakage) depending on which parent was the White. If they were dom white based, then 100% of offspring would also be white with some red leakage. This bird has no red whatsoever, and it has distinct Columbian-type patterning which couldn't have come from either a RIR, RIW or combination thereof.

That's puzzling because I don't have Delaware hens. I have two hens that are solid white and definitely not leghorns. I got them from ideal hatchery in an assortment. I suppose my Rooster could be a New Hampshire if that makes a difference

According to the chicken calculator, RIR's & NH's DO have the columbian gene. Your white hens could be white Plymouth Rocks which are usually barred silver under recessive white, but since you can never tell what the white is hiding, maybe, genetically they are barred silver columbian. Still, I would expect some red leakage on the shoulders or a yellowish cast to some of the white. It's hard to know what genes are really in the mix till you do the breeding. .

The hatchery Rhode Island Whites are Silver based. Ideal uaes them for producing their Red sex links..

Did you breed these yourself or are they from a Hatchery?

Silver has nothing to do with making an all-white chicken. You cannot make a solid white chicken with just silver. You need either Dominant White on Black or Recessive White in anything. They may or may not have silver.

For an all-white chicken with dominant white neither the dominant white nor the black needs to be pure, the chicken can be split for either or both of those genes. If they are split and not pure there is a much greater chance of leakage, though leakage is not guaranteed. If silver is present it will lessen the chance of you seeing red leakage though it can still happen. I’ve seen red leakage on Meyers red sex link males based on their Rhode Island Whites. Those birds did not have barring. A hatchery bird is not likely to be split for either gene, but a bird from someone’s flock might. If the genes are split, you can have a lot of other stuff under there.

Since Ideal uses them for their red sex links, it’s pretty sure they are recessive white and that they have silver. Recessive white is really powerful when it pairs up, it can hide practically anything. But if it is split, it’s as if it is not there.

My guess is that the mother is pure for recessive white, has silver, and has barring hiding under the recessive white. That’s not unusual, breeders often add barring to white birds to make them look even whiter. The solid white mother is going to be based on one of the red genes, could be anything other than Birchen or Extended Black. That pattern is classic Columbia. That cockerel does have the color and pattern of a Delaware, the barring does that.

If you crossed that hen with a black rooster, I’d expect you to get black sex links because of the barring.

Yes I hatched my own
