Note the girl above .. mine..doesn't have that dark of a beak. Lighter chicken. Buff. If you look up the Buff silky you will see most aren't real dark..here is a photo of a Buff chick like yours. Beak is about the same color.
Now I'm looking at the tail again..hummm.... silkies can be tricky..at times. I used to go by the sweep or no sweep of the top, early on. Plus, the width of the comb.
This thread popped up on my page again. Let's see if I can find another silke photo. 😁 Or two, or three. I sure miss them. Wish I was well enough to have chickens again.
