Hello all! We got these ducklings from agway and were told they were Blue Sweedish. Henry definitely is...I think!...but Victoria definitely is NOT! They are about 6 weeks old and she has developed a body full of brown and black feathers a white colar and a crest on the back of her head! She also has shiney green feathers emerging on top of her head and her cheeks. I am assuming she is at least part Mallard. Any guesses?
