Click on Belgium Blues and it gives a history of the breed. It if doesn't give all the info you want, there's an address at the end for the breed association. They can probably answer any more questions.
A few years back when Belgian Blues where a new breed I did get some stakes from a Fullblood Belgian Blue and it was the best meat that I have ever eaten.
At one time here in the USA there where over five different Belgian Blue Assn.
I did hope and think at one time the large Turkey breeders and the large commerical Turkey opperations would understand and know how to raise and produce Belgian Blue meat on a commerical scale, with all of there high tech back ground and with all of there capital, I did think they could make some head way with the Belgain Blue breed on a large commerical scale.
There are some managment skills that are needed to raise fullblood Belgain Blues in a large commerical operation.
If I could buy Fullblood Belgain Blue meat I would do it, but so far there is nothing localy being marketed!
Where I am located at I do not think that Belgain Blues could deal with the high desert temps, I live about 130 miles west of Death Valley,CA.
