Crele

What colors would you have to cross to produce a Crele type bird???

Crele can be created on either the e+ or eb allele. It is barred added to Gold Duckwing (wildtype) . The B/B rooster looks a bit light, compared to the B/b+ rooster, which like the B/- hen has one dose of B. Avoid Di gene.
or Crele can be created like Cuckoo Partridge, as in Wyandottes.
wildtype crele: e+/e+ Ar+/Ar+ s+/s+ B/B or B/b+
(translated: 2 copies of the wildtype allele; 2 copies of autosomal red gene; lacking 2 copies of Silver gene i.e. the bird is gold; 2 copies of the Barred gene; or just 1 copy of the Barred gene)
Cuckoo Partridge in Wyandottes: eb/eb s+/s+ Ar+/Ar+ Mh/Mh B/B (B/- hen)
( translated: 2 copies of the Brown allele; lacking 2 copies of Silver gene i.e. the bird is gold; 2 copies of Autosomal Red; 2 copies of Mahogany; 2 copies of the Barred gene; 1 copy of the Barred gene in the hen).

Karen

thats correct, and the cool thing about crele on both e+ or eb is that they are autosexable...

Haha, Is there a translator in the house??

I guess I need to get that book!

So If I crossed a Barred Rock and a Partridge Rock, I would have a chance to produce a Crele type bird? If so what sex has to be what?

you wont get Crele birds, you will be Barred birds? why? well Barred rocks are Extended Black at the e locus(E/E) and Partridge Rocks are eb brown at the e locus(eb/eb) and the order of dominance of the e loci is... E/E >ER/ER>eWh>e+>eb as you see eb brown(partridge rocks) is recessive to E so your first cross is going to be E/eb B/b and they will all look Barred..BUT... if you cross those birds back to Partridge you will get 25% Crele birds and 75% Barred birds, mate the Crele looking birds together and you will get 50% autosexing chicks.(or at least you will be able to see the double barred roosters)

this is how you will do the mating...

Barred Rock rooster mated to a Partridge Rock will yield 100% single barred black down chicks

select the best Barred rooster out of that mating and mate him back to a partridge rock hen(mother or another partridge hen) this will yield 75% black down chicks and 25% partridge down chicks, cull all the black down chicks, out of the 25% partridge down chicks you will get 50% Crele chicks(as you can see in this hatch you will need to hatch lots of eggs, I say at least 50 of them to get a few crele chicks)

select the best Crele birds(male and female) mate them, out of this you will get

25% double barring Crele males that will look like this(male on the left)


25% single barred Crele females(females can only be single barred never double barred) that will look like the chick on the right.
25% single barred Crele Males(B/b) that will look like the chick on the right(single barred males and females look alike)
25% none barred partridge Females(no headspot at all)

you have a very cool project on your hands

What if I put a silver penciled rock it the place of a partridge? what would that do?

 

[jhamblin]

silver crele?

 

[nicalandia]

silver crele?

no, you will get barred silver penciled rock, just use the partridge instead, much easier...

 

[jhamblin]

Thanks!!! I Have Barred rocks, Silver Penciled Rocks, Partridge rocks and New Hampshires, and I am just trying to get a feel of what I could make.

This crele look seems like it would be the way to go! But do you have any other ideas?
