Truth or not...blue birds

Why? I guess I don't understand what prevents double lacing or spangling on a blue bird.

I am enjoying this topic--and learning a lot.

My guess is that the action of blue is to immediately clump (and thereby dilute) all black in the "middle" of the feather and only on the edges a build-up of black (think: clumps) can occur. The nerves are edges also.
Look at those blue cuckoo hens in this topic without the overall barring. This is the same re-distributing action of blue i.m.o.
Only in tailfeathers (big area's) it can not "undo" the barring.

As to lacing on blue.
There are 2 types:
1. Proper andalusian type of lacing with actual lacing genes.
2. Blue "prone" lacing.
The 2nd type means that Blue tends to form an optical lace around the feather. Melanizers should affect this: more black pigment means more black pigment to be pushed against the rim of the feather.

It can be: Pg Ml Co. Is confirmed in scientific literature for one line of andalusian blue chickens.
But since you can't get double lacing on blue, that would work too: Pg Ml co+ (no Columbian)

Pg or Ml alone could work also.
Pg alone is no melanizer so you might lack pigment for a decent lace.
Other melanizers could jump in though.

Now I'm getting confused.

I'm fine with Co, Pg-Ml or even Pg-Ml making the tidy black lace on Andalusian blue.
But if Ml or other melanisers also make a lace would this be the same as the edging? Because if Ml or other melanisers make a lace & blues have melanisers, & often, I'd have thought, Ml, otherwise they'd be washed out (wouldn't they?) then wouldn't this & the cause of the edging be the same?​

Krys,

This concerns Ml only.
Other melanizers do NOT act the same as Ml does.
Ml influences patterns a lot. Charcoal does not.

In a way Ml is more important for lacing than Pg is!

Thanks.

So Ml would cause proper tidy black lacing, as in nice andalusian blues, but other melanisers are responsible for the darker edging on other blues?

 

[Henk69]

No,

Ml would do it on purpose, others would do it by coincedence.

I don't know the quality that Ml alone would deliver.

Hope that makes sense.

.

Sorry I'm being dense here.

It?
Ml would cause proper black lacing as in blue andalusians & other melanisers might by coincidence?

And the blue edging? Is that caused by melanisers but not Ml because Ml would turn it to proper black lacing (probably on its own & certainly with Pg)?

I hope I've got it this time.

 

[Henk69]

it = making lace, darker edge of feather

I think you got it.

blue edging would be the lack of melanizers i.m.o.

 

[BamaChicken]

So edging and lacing are two totally different things? If so do you have photos to explain what exactly you mean?
Is this lacing or edging?

The reason I am asking is I have some blue pullets with wider lacing around the tips of the feathers. Is that wrong?

 

[BamaChicken]

forgot if you edit it doesn't move the thread. Thanks

I misunderstood the blue edging thing:
I thought that a blue feather with a blue edge was meant, not a dark edged one.

Lacing = proper lacing
edging = blue prone lacing?
