well, texas A&M is a "line" of the recessive white, single pied, color of the coturnix quail, not the name for the white color.
actually the original texas A&M were brown birds...bred by Dr. Thornberry an ag extension specialist with T A&M Univ
and the Texas A&M strain has been backyard bred to smithereeens to where they are basically just jumbo whites.
very few breed to the single dot and weight standards set by the university 40 years ago.
if you hatched a white chick from brown parents then both of the brown parents may have been "splits"
visually brown with a recessive white gene, when 2 "splits" meet up you get a chance for white chicks.
I breed white to brown splits and they are some of my best birds.
good luck.
