Well, I'm in Charlotte, NC, and have some ducklings, but it's a bit of a drive. I have three that I'm willing to part with, all hatched last weekend. I have had excellent luck introducing ducklings within two weeks of age of each other.
I am offering them for only $2.50 each because two of the four I'm selling are very small and scrawny-looking because their down never fluffed out. They are healthy and I believe they will be just fine, but they look funny. If you only want one, that would be fine too since he's going to have a friend. The full-sized fluffy ducklings are $5 each. But the little ones might be just what you need for your newborn.
I'm located close to I-85, so it's a convenient location once you get this far. If you google Byrum Drive, Charlotte, NC 28217 it will give you a good idea where I'm located (that's not actually my street, just the general area--I'll send you an address if you decide to come). You can email me at heather at careyhead dot net, or PM me here.
