Shubin in reference to your earlier question about Mexican the red birds are just a lot more common than the blues. Grey's are a lot more common than the blues as well. Blues are considered an off color by most in the game world so are not as popular or wanted a matter of fact. This board has a whole lot more blue talk than in general and I think others would agree
Truth be told blues are looked down upon
I would venture to say blues make up maybe 10% of all fowl on yards but those that have them are dedicated to them
