Similar to Call ducks, but easier to keep. These are not a bantam version of a Silver Appleyard, their coloration is more like a bantam Welsh Harlequin. In the UK, these are known as Silver Bantam ducks, and what they call Mini Silver Appleyards do not exist here in the US at all.
Everything about the care and housing of Australian Spotted ducks applies to this breed. The birds and eggs seem to be slightly smaller, but that is rather subjective.
