The red pyle color pattern is built on the wild type gene in birds. If you are going to make an ameraucana in red pyle you are going to have to use a silver ameraucana to introduce the wild type gene. It would be best to build the proper black color on a gold wild type then introduce the dominant white.
If you are trying to make a red pyle on wheaten or extended black it is not going to work. It will work on the wheaten males but not the females.
The females must have a salmon breast and that comes from the wild type allele.
All of the pictures so far have been awesome looking birds

Thanks Tim. Actually, I'm backtracking now to better the breast color, since I wasn't getting great results. The pullet I have with the nicest breast color so far is close to point of lay, but she's lacking in other areas, like no beard and muffs. If it ain't one thing, it's another! She also has sooo much "stippling"???...is that the word? It's late and I'm tired, but that word just doesn't look right to me now. Anyway, I only have this one photo of her, and she's muddy from all the rain we've been having, but you can at least see the breast. She does have really nice leg color, so if she lays a nice blue egg too, I think I'll go ahead and use her.
I've only had two chicks without muffs and they both came from the same hen. I'd culled her and put her in with my free range flock, but then realised I was getting the best breast color from her too, so she may be invited back.
Recently I've hatched several good BBR chicks out of my BBR EE hen, and I have one chick from that hatch that picked up the dominant white from the rooster. I lost track of which one it was though after I forgot and put it with another batch of similar looking chicks, but I believe it's a male, and I think it's the best male. He has the whitest breast. We'll see.
Someone just happened to offer me a red pyle OEG Bantam cockerel recently. I don't raise them, but I took him and put him in with one of my last batches of chicks to compare color and pattern. I think a few of the chicks look promising.
