Solid neck vs pearled neck pattern?

OMG! This one! LOVE that color!

Is this your're bird? If it's, I'm gonna guess and say you live in Australia?
Peeps! We NEED some of those birds over here in the US!

I have this color...mine just don't have the red eyes.

Yes I have the Cinnamons in my flocks, no red eyes tho. The red eyes seem to be unique to Oz. And besides not having the red eyes, another difference in what I consider Cinnamons in my flocks is that the skin on their heads and necks has more pigmentation... more brownish than pinkish, but they do have the pinkish hue when they are younger.

Here's Mr Cinnamon

And a couple of Hens (one with neck pearling, one without

)

ETA these are 2 of the 4 that looked identical as TB keets

Looks like the blurry Lavender in the background has neck pearling also.

Totally OT - sorry.....


But if I did not know better - I would think this bird has its wide beak open and is sticking its blue tounge out at me.

Yes it is my bird, but I didn't breed it, & yes I live in Australia

That is correct, both our silver & cinnamon here in Australia have red eyes (silver product of two mutations, lavender & cinnamon). It makes them unique, but does have disadvantage in that the red-eyed birds have sight issues, so much more prone to predation. I would love some of your normal eyed colour varieties here because they could run with the flock free-ranging, more safely.

You know, just maybe the ? genes/alleles responsible for both solid & pearled neck pattern are different to those responsible for TB down pattern & pied markings? Maybe it was coincidence that factors for pearl neck pattern & TB down pattern just happened to be in the selected birds in the Italian study? Although genes that largely affect down colour only do exist I had thought that the TB down pattern may have indicated some alteration in adult plumage, something like the partially pearled Royal Purple Guinea keets having irregular lines/stripes?

Peeps, are the two cinnamon hens both slightly pied? Can't see the bird on the left too well but does look like a little visible white upper breast area?

Hi rollyard as a long time breeder of guinea fowl in Australia I believe you are incorrect but I would love to read the genteic mapping you have done on the red eye silver, so can you please post.

1- The full history of the mutation please?
2- Can you please let us all know who did the genetic mapping and when?
3- Was it a geneticist in Australia or OS like the netherlands?
4- Even better if you can post the genetic certificate of mapping issued by a geneticist that would be super good

P.s Just curious how long have you had red eye guinea fowl?

Very nice to meet you all

I'm not a geneticist by any means, so I'm only guessing on the causes and relations between neck pearling and TB markings based on what I see in my flocks, lol. Coincidences are definitely possible, in any study... and considering that it doesn't appear that study in Italy lasted too long.... makes ya go hmmmm. Anything is entirely possible...
Now if I had only kept a few normal Pearl Greys from this year's hatches that were not Pieds to see if they had pearling on the necks or not... lol dangit. I'm sure if I had the time and pen space, combined with your grey matter we could get to the bottom if this, but for now all I can do is guess and wonder, lol.

And yes, both my Cinnamons Hens are Slightly Pied... all 4 are actually, and as mentioned b4 they were all 4 TBs when I bought them as 2day olds back in April of 2010. Looks like Mr Cinnamon has pearling on his neck too... and more than likely he was one of their keets.

I dunno about you, but my head hurts, lol.

You probably already know, but over here what you guys call silver is known as a Lite Lavender... a dilution of Lavender (blue gene), but it also carries the buff/tan gene as well. And our Lite Lavenders do not have the red eyes either.

Welcome ozguineafowl... another brain for me to pick, yay!

Hi ozguineafowl, I believe we have interacted before elsewhere on this very subject & experienced disagreement there also. I am quite happy for you to have your own views on Silver Guinea Fowl, as I & others have our own. Based on your vast experience in breeding guinea fowl, much much longer than my own by your description, maybe you could help shed some light on some of the questions you have raised & thereby enlighten us all.

Could you describe, based on your vast experience in breeding Guineas here in Oz, what your views are in relation to Silver, ie, what constitutes Silver genetically, & why/where you believe I am incorrect? I am sure you can help those of us with limited experience with these birds to see more clearly!

Thanks in advance
