Cream Legbar Hybrid Thread

[RobG7aChattTN]

Maybe the more simple way of saying it is to use Barred Plymouth Rocks as an example. The Barred Plymouth Rock is auto-sexing if you breed them pure. If you use the Barred Plymouth Rock hen and breed her to a solid, non-white bird then she will pass her barring to the male chicks only and they will have a big white head spot. With pure BPR breeding the male chicks have a larger, less defined spot than the female chicks but since the females will often have a smaller, more defined spot so you also need to look at the color of the feet (darker on pullets) and a light frosting on the backs of cockerels (females are darker). With the Cream Legbars they get some auto-sexing from having Plymouth Barred Rock in their bloodline. Cream Legbars also get some auto-sexing from having Brown Leghorn in their bloodline (some strains can be sexed by the the degree if their chipmunk stripes). Cream Legbars are easier to sex than either because they have BOTH auto-sexing traits. In a sex-LINK cross you are just using the barring gene and that white head spot to show you which chicks are cockerels.

I'd like to add that there are a lot if people who get confused/irritated when their Cream Legbar pullets have a tiny white pinprick. They expect it to be like a sex-LINK cross where only the males have a white head spot and the pullets don't have any spot (because they aren't barred). The thing is, as with Barred Plymouth Rocks BOTH sexes are barred so both sexes have a white head spot. The difference in the size of the head spot is more obvious with Cream Legbars because other genes (wild-type from the Brown Leghorns) create a bigger difference with the barring. There is a BIGGER difference with the head spot size on the Cream Legbar but that doesn't mean that there never is one on the CL pullets (but usually you don't see one at all).

Thank you for pointing this out. I have a barred rock hen and a CCL pullet that will be covered by a Wheaten Ameraucana. I'm excited to see the cross difference. I'll try to remember to add pictures in the spring when I do the first hatch from this cross.

This highlights the difference between "sex link" and "autosexing" genetics. In both case we are using the sex-linked barring characteristic, but they are working differently. With sex-link, the female parent is single barred (females are never double barred) and the male has no barring. In autosexing, the female is still single barred, but the male is double barred. In order to distinguish the chicks, the sexes must have a different number of barring alleles (1 and 0, or 1 and 2). If you reverse the sexlinked cross (male is barred) then both sexes of chicks get a single barred allele from him. If the female of that cross is not barred (solid black, for ex), she contributes no barring alleles and all the chicks are single barred, making the sexes look identical as chicks.

Autosexing is sometimes a matter of degree, depending on the other traits the chicks get that affect down color. Wild-type down (chipmunk chicks) is the best for autosexing, but some other modifiers, like wheaten and columbian can affect the wild-type colors and affect how sexable the chicks are. This is why a "pure" strain of Legbars or Rhodebars can produce chicks that are not easy to sex. It's not that they lost the barring or wild-type down, it's the other genes that muddy the waters, so to speak.

I realize this sounds confusing as I read it back to my self. Sorry, it's early, if you ask more questions maybe the next response will be a bit clearer.

thank you, that makes complete sense. I appreciate it

Crele EE auto sexing project cockerel . Some Legbar in the mix . Single barred .

Legbar male x Light brown Leghorn . Single barred .
Some rose comb among these chicks . These start of my rose comb Legbar project .

Mom is RIR

Mom is Gold Sexlink

Mom is Welsummer

Mom is Silver laced wyandotte

Mom is Blue Andalusion

Mom is Cuckoo Maran

Ignore these guys they are Amerucaunas (unles you can sex them?)

Mom is Half Cream Legbar Half RIR?

This is the dad of all the chicks Half Cream Legbar/ Half ?



Any thoughts on gender? I'm pretty sure it's improbable to tell at this age but I figured I'd give it a go.

Cream legbar rooster over silver leghorn. .
What will I get? I think both will have chipmunk stripes but pullets will be gold and males silver?

I have this gorgeous girl who's momma is a PB Cream Legbar and Dad is a Silver Sussex.
We've called her Autumn. No prize as to guessing why....

I wonder if it will grow up to be anything like the ones I just posted?

 

[Papa Brooder]

saw the question asked multiple times, but never could see if there was an answer posted. Will legbar rooster over golden cuckoo marans carry on with autosexing traits or vice versa GC marans roo over legbar hens? What autosexing breeds can be crossed and still maintain autosexing characteristics?
