Pacific Crested Sex-link. Green egg layer!

[ladyfaeden]

This thread is to document my project: the Pacific Crested Sex-link.

I have a Cream Legbar female who does not have a crest and I didn't want to use her in my Cream Legbar flock, so I put her in with my Swedish Flower Hens. The babies from this combo will lay green eggs and 50 % will be crested. Next year I should be able to have 100% crested babies by using a Roo who is homozygous for crests. We've just had our first hatch. All 8 eggs hatched but since she was just a few days out of the CL coop, 3 of the chicks ended up being pure CL. Here's the other 5, you can see the boys have very large white spots on their heads. Any ideas of what these will look like when they are older? I know the boys will be barred. I had assumed the girls would be black or blue but the red face is making me wonder.

By the way, my objective with the crest is a small, swedish flower sized crest. I want them to be able to see well so they can be in a mixed (crested/uncrested) flock and not get picked on.

Ah hah found you. I hatched a PSL hen. I have an egg from myrcellia? Pipped that would be a SFH?

Fantastic project. Perhaps I'll try this with my flocks. Really interested in having green egg layers. I do have a question however, I was told that the blue egg gene is passed through the cockerels. I was going to try for a larger blue egg by putting a Legbar roo over a black bresse hen. The Black Bresse lay rather large white or tinted eggs. Am i correct in putting the legbar roo over the bresse hen? I need to do my homework on the genetics side but was fascinated by your project!

the blue egg gene is not sex linked at all, so its not passed thru the cockerels, if the bresse lay white eggs and you use a legbar(needs to come from a blue egg laying type, I think only the crested legbar lay blue eggs) you will produce blue eggers, if you want olive/green eggers you need to breed your legbar to dark egger hens like marans...

Thanks, you read all sorts of misinformation on line. I believe I read the above on a UK chicken forum. I am interested in producing both large and medium size Blue eggs for my Pastured egg line. I also would like them to be a good utility bird thus the Legbar x Black Bresse breeding. My goal is to produce a layer of large blue eggs that can lay upwards of 250 or more eggs annually and be great for the table or pot.

he is only saying that Brown egg color is a polygenic trait, and some of those traits are sex linked, and that a son from the best brown egger carry those genes from their mother, thats all.. white egg shell gene and the blue egg shell gene are autosomal(none sex linked)

ladyfaeden, I'd love to see what has happened with your Pacific Crested Sex-link project!
