Cornish jubilee or white laced red? w/pic

[Ryu]

I definately have eye stripes. My chicks look like the ones on feathersite. So if you can identify from that let me know.

I pulled out Jeffrey (Bantam Chickens) tonight, he lists the E locus as ey.

If all else fails, I will do some test crosses--I am very curious to know what it is exactly.

I'm off to scour the internet for a pic of the elusive ey chick.....

I have that book too. It was good in its day & explained things clearly but It was written in the 1970s & a lot has been updated since then.
A lot of the usual old standard books such as Poultry Breeding & Genetics talk of recessive wheaten (ey). As ey does not seem to be referred to any more I expect that ey & eWh were probably the same gene.
Indian Games are wheaten in UK, which is country of origin. The single laced varieties have not been developed there. Indeed, until David said they were different in US I didn't know they were eb in US. Maybe F.Jeffrey would have been referring to them. Maybe the single laced varieties hadn't been developed in US at that time; maybe they were still wheaten????​

Ryu....Wheaten with nothing else is just yellow but other genes can affect wheaten. My chick Indian Game chicks back in UK, if my memory serves, were yellow with two dark lines. Do any of your chicks double laced chicks look like this?

Mine have eye stripes, a black stripes on the head partially down the neck, and two broad black stripes on the back. No brown, just black and a pale yellow cream chick down otherwise. My WLR are the same pale yellow cream with a red tint on the backs--those look very much like wheaton to me.

I am not an expert on chick down by any means.

I was playing around with the chicken calculator. You can get double lacing on a pretty wide range of e backgrounds.

I surfed the net for pics of Wheaton and 'recessive' wheaton chicks and didn't see anything like my chicks. I finally cruised the hatchery websites and searched through their pics.

The closest thing I've got to them is an Aseel chick from Ideal. Out of 10, I got 8 eb looking (brown down), 1 very e+ looking (black stripes, brown broad stripes, and cream down), and one that looks like my Cornish chicks (black stripes, eye stripes, and cream/yellow otherwise). We will see that it turns out to be.

Mine are almost identical to these: http://www.feathersite.com/Poultry/CGA/Cornish/BRKCornish.html
I see a couple in the pic with brown on their heads, mine haven't ever had that.

Like I said, I am very intersted to see what my very correct colored roo throws as compared to my roos with white/lt gray under color on neck and tail.

Nor me ...but I've bred so many chicks in my time I recognise a few.

It was quite a long time ago that I bred them in UK. My breeders were double blue laced. I seem to remember that there was a difference in the colour to do with the line according to whether the lacing was going to be black blue or splash.

I'm really out of practice.

Is it splash being used for the lacing?
We had various wyandottes ......I remember how the columbian affected the eb on silver & gold laced wyandottes ...but cannot really remember the appearance of splash laced red chicks; I have a notion the blue & splash laced chicks were an odd colour. Could splash be affecting the colour of your chick's down?
Look at the blue laced wyandottes here ....they looks light, splash could be even lighter.

The old Dominant Wheaten eW and Recessive ey were in fact found to be the same allele. Wheaten, now written eWh, without modifiers is Dominant to Duckwing e+. However when modified with 'recessive blacks' it becomes recessive to Brown eb. An example of the recessive expression is the RIR.

Which genes or genes alter the dominance?

E > E^R > eWh > e+ > e^b > (eWh + ???)
