Rejects?

Ive had these silkies for a few months now, got them from a lady. I think she gave me her rejects 😅 But they are the sweetest little things! They dont know how to be mean. Any silkie experts here? Are they possibly imbred or something? Their poof looks pitiful lol, one doesnt even have the poof it has mostly regular feathers with some poof underneith
