I think they are more likely English whites everyone calls the Texas A&M quail but from some reading and watching videos the A&M’s have all white meat and apparently according to one guy if you have A&M’s you know you do because you have proof of lineage or something or other just regurgitating some information I found
I think your right that they have english whites or reccesive whites not A&M. Easy enough to tell. @Maiahr are the birds solid white or do they have Any color? I have had A&M the 'all white meat' isnt true.
A&M have same meat as other coturnix. They have white skin for cleaner presenting carcass. They are a specific strain of coturnix created using birds with English White color and jumbos for size. Texas A&M bred them larger so they would develop white meat but they could only get up to almost a pound and no white meat materialized. Technically a person doesn't have A&M's (which are jumbo sized) unless they know their birds come from that strain. Most people actually have English Whites (which are not usually jumbo sized).
