Small non-aggressive goose, friend for a Sebastopol UK

[pablo_honey1981]

I have a one year old goose, supposed to be a Sebastopol. Bought the egg from a seller who claimed the parents were both fully curly whites. My goose came out white, but completely smooth. She has bright blue eyes. I dont know if she is a smooth Sebastolpol or an Emden. She has 4 ducks for company but I want her to have a goose friend because everything I see says they'll be unhappy on their own. Thing is I dont really want another massive dominating goose.

Could anyone recommend a breed of goose I could keep domestically in the UK that is small, docile and would make a good companion for her?

Or am I seeking a unicorn?
