yes... but is best to use a Pea Comb breed that carry the blue egg gene linked to it best.. that way you care sure to have around 94% of your pea comb birds to carry the blue egg shell gene if you decide to cross back to marans...

What breeds are blue egg layers and pea comb birds? That are also quite common

Ameraucanas(bearded, with rump) Araucana(tuffted and rumpless) and EE, Easter Eggers, but you would have to make sure the EE being use carry the blue egg shell gene, so using a EE hen that lays blue or green eggs is a must

Excuse me, but reread the part about the 4 females used. They were ROSE combs and layers of BLUE eggs. The rooster was Single combed and non blue egg. The British Auracana does have a crest and a tail and Punnet was British. Now you may argue that these British Auracana below have pea combs and not rose but they are definitively not single.

You can get straight combed crosses. When I breed my Penedesenca rooster and ameraucana or U of A hens I get 50 / 50 straight and pea combed. If they send straight combed chicks they could not tell you they would be olive eggers. I had a few Barnevelder x ameraucana straight combs lay olive but that is not the norm

I don't see how it would be possible to get any straight comb chicks from an F1 crossing of ameraucana and any straight comb chicken. The Ameraucana must carry 2 pea comb genes to really be considered pure bred and pea comb is dominant over straight comb thus 100% of the resulting chicks should have pea combs. 2nd generation cross back to a straight comb chicken will yield 50% straight and pea combs. F1xF1 cross should yield 75% pea combs with 50% being heterozygous for pea comb gene.

Excuse me, but reread the part about the 4 females used. They were ROSE combs and layers of BLUE eggs..

Re-Read that again and come back when you have realized that the hens were Heterozygous for the rose comb(R/r+) none of them carry Pea Combs, and Why they had only one copy of Rose comb? because these hens were F1 products of the Chilean stock(single comb r+/r+) mated to Hamburgs(R/r+)...


so no no Araucana/Ameraucana blood in them, but you can argue that the Ameraucana or Araucana can trace their lineage to some parts of Chille and South America


here my take from last year

you care correct... Pure Ameraucanas dont produce single combs in F1 crosses...

sorry did not read the first cross part.Yes correct.

should also note I have sold all the U of A crosses at day one and only hatched a few so i have not kept much track on them yet.
Ill be hatching more of those once I put my silver ameraucana in with the crele penedesenca this week,
The U of A blue's will be in with my White Empordanesa.
