That's been in the back of my mind too. My local feed store guy said he can get me some when I'm ready but I'm pretty sure those are hatchery birds. The next order of business would be to find a good breeder. I figure I'm in the right place for that.
Here are a couple places to look at Delawares here on BYC ...

(that's in the "serious" forum, so more for informed discussion about breeding challenges or showing, but with some potentially helpful contacts and/or visuals)
