I take that to mean that McMurray doesn't care whether their Whiting True Blues have muff/beard or not, since they feature photos of birds with and birds without.
I though Ameraucanas were supposed to be a dual-purpose type chicken, while the Whiting True Blues appear to have more of a Leghorn type.
We have so many breeds that lay brown eggs, and so many that lay white eggs, I think there is room for quite a few that lay blue eggs as well. Personally, I'd like to see a breed with just normal chicken traits that lays blue eggs. No muff/beard, no ear tufts, no missing tail, no crested head, etc.
