@Fueron Thank you!! This ties up with the vague and incomplete descriptor when I fell in love with them at a local smallholders (did not realise how rare they are, although they were expensive for chicks), and what they look like, and some similar suggestions I've had from some very helpful people on BYC. I think the descriptive 'quail' has been very confusing for both me as an actual quail breeder, and the search engines, which are throwing up the usual boatload of information, but nearly all reference game quail.
So just to clarify when I reach out to breeders for unrelated bloodlines, what I have are:
Barbu de Watermael White Quail with the Buff variation ?
You can just call the color white quail
