The IMPORTED ENGLISH Orpington Thread

"Isabel" genetically is Lavender diluted Crele. Crele is Cuckoo/Barred Partridge. Lavender, is Lavender. It is it's own gene and is sometimes also referred to as Self-Blue.

The reason Isabel "looks to be just a lavender with tan/gold leakage on the hackle, saddle, and shoulder feathers??" is because Lavender doesn't only dilute the black based parts of birds plumage but also the red/orange parts of the feathers. So the black barring turns pale gray (Lavender) and the red/orange of a Partridge bird turns yellow/pale gold.

The pastel hue of the Isabel color makes it hard to discern the bird's pattern. Conversely, depending on how well patterned underneath the Lavender dilution is could attribute to the lack of definition in the bird.

Breeding a Black cock bird to a Isabel hen will produce single barred male offspring and solid Black female offspring. All with red/gold leakage (especially in the males) and all recessively carrying 1 copy of the Lavender gene.

Breeding a Isabel cock bird to a Black hen will produce single barred male offspring and barred female offspring. All again with red/gold leakage and all recessively carrying 1 copy of the Lavender gene.



I guess I'm gonna be in the market for English Lavender/Self Blues soon.

Thanks Jeremy, it all makes more sense when you see it in writing :)
 
Thanks Jeremy, your posts are always helpful!

I knew Porcelain was Lavender x Jubilee... Don't know why I said Mottled, I guess I have too many birds on the brain right now.. HA!
 
Have any of you noticed if there is a correlation between the start of surging hormones (pink faced) and the slowing down in growth in the pullets? With my cockerels I have noticed that by the time they have a good sized comb and wattles, with red faces (6 months or so), they don't get any taller, just get more girth.
 
I would love to see a Porcelain English Orpington...maybe I should start on that project too

it is about the same with the pullets as far as I can tell...they just start gaining weight and getting wider at that point.
