Second chick in latter images and lower right in first image with all three. It does have the grizzled down look of a gray, just not as strongly so. That may maybe your gender marker, I have not played with silver on e+ background that much. If a gender marker, the females have only one copy of the Z-chromosome where the silver allele resides. If it is a male, then it could be heterozygous for silver where one Z-chromosome carries the silver allele and the other does not. Birds that are heterozygous for silver allele with be golden duckwing why those that are homozygous will be silver duckwing. Females will have only one copy of silver or none.Oh okay, so it may not be a flarry eye grey at all?
I am pretty sure I have seen birds marketed as Flary Eyed Grays appearing as black-breasted red or wheaton even though the Gray part of name implies they carry the silver alllele. Either way I think they are pure enough for your interest.
