Black, Birchen or Something else?

[CascadiaRiver]

I made a mistake and had a friend convince me to take home a black OEGB chick with my booted bantam from the show and now I am trying to think of what this thing is colourwise. Its SOLID black besides white toes and a bit of white on its buttfluff. He breeds black, birchen, and its been a while since I've been at his house so I dont know about any new projects, what are early feathering signs of birchen vs black?

you will have to wait until their adult plumage starts to appear. Look for nonblack feathers in the hackles of the male or female. Birchen will show some white in the hackles.
