When Embdens are young they often have a few grey feathers. Especially females. Time will tell but my guess is female Embden. As I say all the time, I am not an expert on geese, especially Embdens. An Embden that I had last year had a few grey feathers till it was processed at 20 weeks. I read somewhere, I think from Dave Holderread that females from white breeds such as Romans, Embdens, and Sebastopols, may carry a few grey feathers up till a year. After a year they should be all white. Hope that helps.
