Ah! Forgot to get those photos. I promise to try at the weekend. I’ll show you some photos I have of when they were younger, this won’t show their type but the feather colour is still there, and that’s what you care about for now.
You can see that the neck itself is still very pale, a cream colour (hence the name!). I haven’t checked the suggested ‘SOP’ for a while, but I think it should be almost silver with a very light hint of gold. The thing I noticed with yours was the breast. Notice how mine are obviously different from the rest of the feathers, a salmon colour (orange/pink). This should be the warmest coloured area of the bird.
When I get the new photos, I’ll get some photos of some other chickens to compare them to, to show you what I mean when I say they are lacking Autosomal red.
Hope this helps.
