All black chicken breed? Any ideas what breed?

can you give us the age of the bird, and a good, clear shot of the side, an up close of the comb? The person's arm around it blocks our sight of most of the bird's features

 

X2 on that. All full body profile showing head, legs, and tail will work best. )

 

Ayam Cemani are an all black chicken, they are very rare though. Where did you get her?

It could also be some kind of throw back, like if a Silkie were mixed in at some point. They also have black skin (and bones and organs, if you looked inside ).

 

She looks to be a dark blue. I can see lacing on her feathers, and the darker blue of her head and neck. Is she a bantam?

 

She looks blue to me. Probably an old English game bantam. They come in blue. They also have single combs just like the hen/pullet in the picture.

 

Ahhh, she does look blue now that I'm looking at the picture on my computer! On my phone she looked pretty black! Maybe a blue Sumatra?

 

I'm almost positive she's a Blue Old English Game Bantam.

 

Most likely she is a blue old english bantam, but she could be black if the lighting is off.
