Hi, My friend has hatched out her second lot of Welsh Harlequins and one of the babies is crested. The adult ducks came from me and I have not had anything crested in the 4 years I have had them. I get the Karki Campbell throwbacks but never anything like this. It is too cute. Fow whatever reason I am unable to upload photos but will try again later. Has anyone else ever had a crested duck that should not be?
