I think Embeden goslings are all fuzzy yellow fluff. She looks like she could be a mixed breed possibly but you may have to wait till she is fully grown before you know for sure. I know female Pilgrims, Cottonpatch, and I think Pomeranians have patches of grey and white, but there are probably more that I am forgetting. I only have American Buff, so I can't help with the specifics. She's a beautiful goose though !
