I bought 4 Silver Spangled A-S pullets this week. They are quite inconsistent: their plumage is similar, one is quite a bit darker with a much bigger crest; one has an almost minimal crest. A couple have blue ears, a couple pink. A couple have beards, the others not.
These are supposed to be hatchery purebreds but I'm wondering why there are differences between them.
These are photos of two of them:
