can double factor spangle budgie posses slight kind of marking or it should be pure in color?
If it has iris rings, it's a double factor spangle for sure. I can't quite tell from this picture. The cere also looks kind of purplish and usually DF spangles have normal blue ceres if male.actually i wanted to buy a DF from a friend,his bird's color was almost same as in this picture,with slightly dark feet and cere ?
Should i buy that bird as a double factor Spangle?
