How would you create this color, and are there any traits( leg color egg color ect) that it affects?
How does isabella differ from say like wheaten? If you look at a wheaten old english bantam I think it pretty much looks isabella, what you you think?
Egg color is only affected by the bird and/or breed, not by color. Leg color is the same in most cases.
Isabel is mainly the term for Lavender diluting the gold in patterned colors like lacing, partridge, wheaten, etc. So, it all depends.
Do you want to introduce it to a mutt, a purebred and what breed, what Isabel patterning do you want or does it matter?
All depends on what the variables are.
Quote:I just happen to stumble upon the Isabella leghorn and brahma projects.i was thinking if you needed to cross one breed to another it might affect the traits I mentioned.i have some longtails that I would say are a blue ginger , some mottling and some lacing. If someone has some breed in the color I would be happy to see pics please? I also have pure blue wheaten ameraucana , so how would you proceed?
In order to get Isabella without having it to start with you would have to cross Lavender to the color you want to have diluted by the lav gene. For instance to make Isabella Leghorns you would cross the Lavender with either Brown Leghorns and then cross the offspring and you should have some Isabella pop up after the 3rd crossing.
The genetics of the Isabella Leghorn is Lav Diluted BBR and would be easiest made in OEGB in the US.
Isabella Leghorn from the Leghorn Club of Australia's website
OK, so I know I am reviving an old thread... but I just stumbled on the term Isobel or Isabella and found the Brahmas and Leghorns and they are stunning. I read the description above, but being painfully new at this I would love a little more info. I have a lavender Ameraucana roo and I have Brown Leghorn pullets. If I understand the instructions above I should cross the 2, then cross the siblings, then cross their children, and then again a 3rd time I should have some pop up? Or is this one of those cases I've read where I am supposed to continually breed back each generation to a lavender (the original rooster or another one) in order to further dilute the original coloring? And either way - how do you breed to continue the trait? Will it be self perpetuating after the 3rd crossing? Or is it like sexlinks where each generation must be created from scratch and then will not breed true?
Thanks for any help, I am just beginning to learn all this
Isabella to Isabella will breed true but in the early stages, you'll need to breed your Isabella pattern birds back to Yellow Partridge or Brown Leghorn foundation birds. Isabella males to Brown Leghorn hens and Isabella Hens to Brown Leghorn Cock birds. You'd take the males from the Brown Leghorn Cock matings and the females from the Brown Leghorn Cock- Isabella hen matings and cross the progeny together. Select the Isabella pattern offspring and rinse and repeat until the birds have yellow legs, white earlobes and are laying chalk white eggs and look like Leghorns in type and size.
I reckon this could take 5-6 generations depending on what bird was used to introduce the Lavender gene to begin the entire process. I would avoid Araucnas due to blue egg, beard, crest, leg colour etc. This would take a long time to breed back out.
My thoughts anyway.
Again, reviving an old thread.
To get Isabella coloring, without having it to start with...
1) Does it have to be the roo that is lavender? Or would it work as well with lavender hens under something like a brown-red Ameraucana roo if one were wanting to create Isabella coloring in Ameraucana?
2) Does this only work with certain breeds or are there people working on Isabella coloring in other breeds?
There are some people working on a Isabella wheaten Ameraucana already . Check out the club web site . You may be able to contact someone who has them.
This can work on any breed with the right color .
