My point is that I don't think there is a defined type yet is there other than being BBS, pea combs and laying blue eggs? Considering people are still getting variety out of 'pure' stock (ie recessive white popping up out of BBS stock...) also I remember some people on rare occasion getting straight combs from the originals although I think people are doing a better job of selecting now.
I am not at all saying one should intentionally breed away from what they look like at the moment, simply saying that the original designed intent of the bird is not appearance and body type first(which is yet to be defined), eggs second. The original bird was bred for a specific egg laying roll, the appearance that came about just happened to be.
These should have a specific body type. Their shape is very similar to that of a Sumatra. The only big debate that I have been involved in was whether legs should be yellow or green. I prefer the willow myself.
