Query about a goose and a duck!

Hi everyone!

I would be very grateful if anyone can help me with ID of these from S. Yorkshire.  

One is a white goose with black on the head (two photos).  Also, are the issues with the feathers because it's a juvenile? Or injury?  It was with Canada Geese, but doesn't look juvenile images of these.

The other photo is of a duck nearby - at first I assumed it was a female mallard as they always are here... but it doesn't look quite right. Is it just a female mallard? Or could it be a gadwall or pintale?

Thanks so much Slight smile
