I bought my chicken (Olive) as a chick almost four months ago, and i'm not sure what breed she is! She is quite small (around 25cm-ish?) and I think the breeder may have said she was a bantam something, but i'm not sure.
She is not laying yet, and has a golden head and black body. Her crest looks sorta like a rooster, but she's not crowing either (there were 2 roosters in the same batch I bought, but they started crowing 2 months ago!)
