TV,
No one meant to offend you, as it sounds like that has happened. Just trying to offer advise and opinions. There are certain things to look for and certain things you dont want in them. By claiming 7/8, it usually shows a bird that can not hardly be distigusished from a pure, pretty much reguardless of pheno or genotype. If you got them and a pure in a pen together, you about couldnt tell them apart, heard of many breeders having that problem.
Both Doug and Deerman are highly seasoned pros at this, but no one meant any offense
