Blue Sweden duck changing color

[Duckieduck]

My blue Swedish duck is molting and as her new feathers grow they are white, when she originally was a dark grey. Her entire head is white now. I adopted her last year and was told she was a year old, but I don't believe that because her feathers are quite tatty and her bottom drags on the ground. She looks nothing like my young ducks. Is her changing color a nutritional deficiency or just age? Thanks in advance.

Normal for the breed....They get more white with age...

Oh perfect, thank you so much! Do you know what age they start to change? It would be nice to have some range for her age.

After each molt they can whiten up more...possibly a year ?

Also, Duck Hens butts do bottom out with age...Like many woman do.......Kidding!

Can you post some pics of her? The bottom dragging on the ground could just be that she is of laying age - some of us call it a "ba-donka-duck" butt.
