Lavender patterned Isabel duckwing barred - lavender brown cuckoo barred - project and genetic dis

[ChicKat]

Hmm no..she doesn't play house. She is the first, when I walk up to the coop to let them out, to greet me with her purrs...the only one who makes these sounds.
She will stay right in front of me almost begging me to "pet" her.

I will take a video tomorrow.

Yay - I can't wait to see it. Those are the kinds of chickens I really like best -- the friendly ones.

Do you see what I see?






Stop the presses! Rewrite all the genetics books.... big 'to do' or is it 'ta da' ?

First big picture appears to show a lot of strong white feathers in the tail. This split has Isabel male and CL hen for parents. Lots of blank white is considered undesirable BTW. This guy, as you can tell from the parentage has only 1 lavender gene. Look closely at the sickle feathers in his tail and see that in addition to white there is distinct lavender showing. He must have a really powerful diluter in his one lavender gene - because as I understand it that feather would otherwise be black. (lavender gene doesn't work on white, now does it?)

So for years I have been batting the Cream Legbar people over the head with my 3-ring binder saying 'NO - one copy of a recessive is just like zero copies of a recessive'. We've heard of 'incomplete dominant' but I've never encountered 'incomplete recessive' - or like 'semi recessive'

Could it be that the joke is on me... Does that look like lavender in his feather to you?

I wouldn’t put much on that, from my end it just look like normal white tail feathers that some roosters develop, I see them on game stock and on CCL,



And that is the only reason recessive lavender is showing, recessive genes like lavender will show some or partial expression in the presence of other genes, defects.

Lavender even in recessive form may interact with other gene, for example on this post by Sigrid Van Dort http://www.the-coop.org/forums/ubbthreads.php?ubb=showflat&Number=96971 lavender was found to inhibit the powerful dermal dilution effect of barring in the presence of Fibromelanotic

Thank you Nicalandia.....

This bird is B/b+ by the way -- and if the pict doesn't show it -- it actually is lavender not white in those tail feathers -- especially noticeable next to the white feathers. Another thing that is kind of wierd is this: When my CLs get the white tail feathers they seem to grow in ultra fast -- like there not there one day and the next day they are. The white ones (and they are only partially white) seem to fall out in a few months/weeks -- and not in conjunction with the molt.

Thanks for the link - interesting stuff.

Every now and then it helps to just google what you are looking for. This morning I googled 'Isabel cuckoo' . Still only showing Orpingtons - along with some photos from this thread. (because it is under discussion here) -- and then I found that MyPetChicken has Isabel orpington eggs. Six eggs $79.45, and pretty bird as the example - here is the picture from My Pet Chicken's site:

You will probably have to right click and open in a new window or tab (depending on your browser) --- and look closely at the left most tail feathers -- ruffling in the wind a bit and see that these feathers appeared barred. -- Which makes it a big confusing. This Isabel Orpington has nice Isabel coloration -- it doesn't look too faded. The tail has a definite lavender and the breast doesn't look too whitened, the hackle and saddles are a rich and creamy-straw color and the wing has a definite bar above the triangle which shows a diluted gold. Right? But are the bars appearing in the tail feathers and (maybe on the saddles) -- due to a barring gene, or is that the way his lavender grew in.

At anyrate -- a nice example of the coloration.
ETA - found another photo of the same chicken from the other side. The look leads me to believe that there is 1 barring gene at work there:

Talking about google, I was doing it this morning and hoping to find some pictures of the chocolate silver laced orpington chicks and had found none. .Yes, those are very nice colored of Isabel orpington

There's that old saying "Great minds think alike" -

Of course you know what that means...when you begin posting pictures from your project, then, that is what will come up on google search. Pretty cool if you ask me.

I know I am not only one who is working on this color, there are several breeders are doing the same though not sharing on BYC yet. However, I have not heard anyone is working on Isabel cuckoo legbar. You will be the first one!
Oh, another question, will you continue breed isabel leghorn after you finish your current project? If you ever need to downsize some of your adult isabel birds, I would like to buy a few

Sounds good to me. You are at the top of the list.

ETA, there are others working on the lavender crele Legbar look too --
