They are very cute, fun little critters & the eggs are outstanding as well as being a great source of food for monitors.
Your white quail is an English White or Texas A&M. Both are color variations of the Coturnix (Japanese) Quail.
A&M University did a project to breed the perfect jumbo quail for harvest, large size & white color for a more favorable looking finished product when plucked.

I keep a mix of color variations (Standard, A&M, Italian, Tuxedo & Tibetan) which makes for some very interesting chicks.
