Duckgirl, please read Holderread's site very carefully. As far as I know, he won't ship bantam ducklings and ships the adult bantams in the fall. Very few places will ship bantam ducklings because they are too small to survive shipping.
You'll have to verify that. I haven't ever bought any bantams, but it seems to me that I noticed that on his site.
I've seen his Spotted Australians and the green East Indies, and both were really stunning.
The East Indies will be much easier to raise. Show quality Calls can have difficult hatches, I suspect because of the extra short bills.
For showing, it seems to me that Calls do way more than their share of winning the big prizes. So that is a consideration of you want to show.
