What breed?

[Brit327]

This chicken is about 2-1/2 to 3 months old. It is the white and black one.

She looks like an Old English Game bantam, silver duckwing maybe? They're lovely little birds!

I have Old English Bantams (Silver Duckwings) and she isn't that. If so she would have more maroon on her breast. They're loads and loads of OEB breeds so it could still be one of them.
