Cream Legbars

Gul dang! I am getting good at this sexing stuff!

The one on the far left has no spot, but the eye liner is not as good as I would have liked. Did I get her right?
You are getting good.

The one on the left had me going for a bit -- because the top of that chick's head looked very light - but I think it is camera angle and light on the chick down. although we use eyeliner -- and I use head splotch a LOT!! -- technically it is the dorsal stripe that is supposed to be the give away. blurred - more indistinct, faded together = male. Crisp, sharp, well defined = female.

Putting on the x-Ray vision glasses to peer into the underlying genes my THEORY is this. Because females can only have 1 barring gene. Maybe strength of that particular B on the B-Locus (B for barring )--- is expressed by tiny white frost in the center of the chick forehead V. Males however, carry two copies of the barring gene. For a Cream Legbar male the barring genes on the B-Locus should be B/B -- two copies of barring. The result of this in the down is the white splotch IMO - and the blurring of the wild type back stripes.....

The double B genetics B/B are already interfering with the wild type chipmunk pattern. Pure Danish Light brown Leghorns will have the same chipmunk pattern male and female. Pure Barred Plymouth rocks (some strains) are all black with males having a white head splotch and females a smaller head spot.

Although I have to say that my quick skim of this set of pictures:
https://www.backyardchickens.com/t/798635/sight-sexing-barred-plymouth-rock-chicks-at-hatch I couldn't really easily tell the difference.

I couldn't tell males from females -- and lines/strains of PR are different... R.C. Punnett used both the BPR and the Danish Leghorn to achieve the autosexing...so I really like birds that hark back to the roots of the autosexing part of the breed.

Thanks that was an interesting read..

I know these are not CL's. I was wondering what I stumbled on that make these chicks have a white spot on their heads, I think you answered it. These are the result of a CX rooster (Yep you can get them older enough to breed) and a Dixie Rainbow (mutt).

 
I hope it's ok to cross-post form the Cream Legbar pictures thread - since you were talking about chick markings, I thought I'd share these. Cream Legpar pullets from My Pet Chicken/Meyer. Clarissa and Jennifer have the more typical darker look I've seen most often in photos, while Paula is lighter and has more interrupted head markings. (Paula is in my avatar at 6 days old.)

Clarissa, 5 days old (mad at me for disturbing her playing the brooder)



Jennifer, 5 days old




Paula, 13 days old (6 day old photo in avatar), with different markings.




I find the difference interesting. They're so sweet, talkative, and, well, rambunctious/messy. Their current favorite game is "how high/far can we kick the pine shavings" - preferred time to play is right after changing the water, of course... Getting a brooder nipple waterer STAT.

I have a similar question on sexing the Legbars. In my hatch, some chicks are lighter color, others dark, some have a well defined white spot or splash, others just a tiny dot. I'll post some pictures and describe my questions.

The one at the right is silve-gold and has a splash. I think this is a male. Is the light color OK?



These are two more of the light color one I believe are males.



In the center there is a normal colored one, but has a speck of white in the center. Male?



Another shot of one with a spec.


Again, one with a speck.
