I can't see them well enough to see if one has the white spot of a black sex link, but to me it looks like two pullets. I believe the silkie feathering is recessive, so unless it is on both sides, the silkie feathered part won't show, but the body conformation just might. If you can cross this with something that has Silkie, Turken, and maybe Polish in it, you could have something really set for Halloween next year. No costume needed.
What do you think about that one in the last photo? Is it looking sad or maybe serious, or maybe still in shock from what it has already seen in its young life. To me, it looks like it has an attitude.
