breed? stray chicken

[AinaWGSD]

Most likely ayam cemani or cemani mix. Maybe cemani/game bantam mix?

What about svart hona? That’s the only other all-black breed that I know of. I think greenfire sells them

 

[OneLostHen]

Black sumatra?

 

[Whittni]

Hatchery quality Sumatra/Sumatra mix (real Sumatras have cushion combs, not straight--so likely a mixed breed or hatchery quality). She's likely very flightly and aloof by nature.
