Barred Rock, Crested Cream Legbar, and male Black Sexlinks would have barring--so your barred chick should have one of those breeds as one parent.
Black chicks could come from having one parent be Lavender Orpington, Black Sexlink, Barred Rock, Ayam Cemani, or Ameraucana (if it's black or blue Ameraucana).
For the other parent of each chick, almost any breed is possible.
--Wyandotte will probably produce rose-combed chicks
--Crested Cream Legbar will probably produce chicks with a small crest, and pullets should lay blue eggs
--Ameraucana will probably produce muff-faced chicks (fat cheeks), with pea combs, and pullets should lay blue or green eggs
--All other parent combinations should produce single-combed chicks with no extra feathers, and pullets should lay white or cream or brown eggs.
(comb types are hard to tell on tiny chicks, but become more obvious as the chicks grow.)
And now I feel strongly that the small almost all black one with puffy cheeks in ayam amerucana mix! How fun. If I mix it back to a pure ayam do you think I could have an all black chicken with green legs?
That might work. I haven't studied leg color enough to know for sure about green legs with black. It sounds attractive to me!
