White over barred cochin..**updated pics**

Good question. I consider pied as having well defined and *separate* patches of white & colored areas like on pied peafowl, pinto horses, many dogs like beagles etc.

Wildly random flecks like the originial exchequers don't have the well defined patches to me- the little spots on a feather & solid colored/white feathers are all over the birds randomly so to me they aren't "true pied".

It has been suggested that exchequer pattern is caused by mottling plus modifying genes. Another suggestion has been that they are incompletely dominant alleles.


I had three different lines of exchequers back in UK. From crosses I did with them I think they had what appeared to be mottling & something else going on. From initial crosses to brown leghorns (e+) in the F2s I got a few different phenotypes. One of which was the smaller white mottles, usually associated with mottling, another of seeingly random white bits not particularly feather tips, & then some which were exchequer type pattern. These on both E & e+ base.

Love it when someone acquires and then does crosses etc to figure out what's going on with them. Did you get any birds that looked close to the bird being discussed in this thread?

No, not at all. the lightest coloured birds were exchequer pattern.

Someone suggested B/?, mo/mo
I have some B/b+ (B/-), mo/mo, young stock at present. I'm just watching these as the pattern is more like B/B than B/b+, possibly even broader white bands than B/B. I'm just watching these to see what happens, but I don't think they'll look the same as the bird in this thread.​

Yes that's what I pretty much thought about B/? momo birds. David Caveny also said barring combined with mottling can make for an auto sexing strain, with the males being largely white.

I have posted this on the-coop.org and below are the two answers that have been posted at this time.

Manok: Barred with mottling could very well be possible. The chick indicates mottling, and if you saw barring, that's probably in it. But then he has he "extreme mottling", or "hysterical mottling", as Sigi calls it.

ruffEnuff: wow that has got me.

i have barred birds split for mottling and the mottling is barely noticable. i have not yet crossed the birds to get double dose of mottling. and i think i will have to use the hysterical mottling to make what you have here.

all i can think of is that it must be 2 doses of hysterical mottling and this must be achieved by both parents having mottling. so i think one of the cuckoos must be split for mottling, perhaps the rooster and then he was crossed to the mottled hen.

however i am only guessing. i think the bird is a very attractive bird and i shall be trying to recreate your bird this season just to find out if my theory is right.

the chick down colour is typical of what you would expect of an hysterical mottle on ER.

Just for fun...take a look at the Cochin in the bottom left of this pic. I hatched him out of a pen with a black/silver roo over black, blue barred, and buff hens. I am now interested to find out what he's going to look like. I gave him to someone at the last swap, but I know who has him, so I'll keep up with his progress. The 2nd pic is his daddy.

Wow, he is just gorgeous..

Love the frizzles too.
