Sonoran is awesome with the genetics and things like that........
Those are still nice hatchery birds......looks like they are not bearded so the crest will be smaller on them.
I grabbed a couple of white featherlegs out of a TSC bin last year, and even though those two (a pair) are way...
There are bearded and nonbearded varieties
Basically, when choosing which bird to show or breed from I go by certain things - not in order I look at........
Color of feathers & skin
Bird size
Comb type and size - I make sure no horns on the comb & it is a walnut comb that is mulberry in color...
