I travel pretty regularly between Delaware and West Virginia. Our farm is in WV but we lived in DE for decades and lots of family still there.
For an area that produces so many broilers and has chicken farms everywhere, I was kinda disappointed by the lack of breeders that focused on heritage or rare breeds in DE. They're definitely around but not as common as I expected.
There is a breeder directory here on the site and those "I am here, where are you" threads can be helpful as well. We will have lavender orpingtons, cream legbars, silkies and olive eggers but none are up to show standards at this point - especially since only the silkies are even an accepted breed/color.
Sorry this isn't super helpful. I'm not sure if any of my old contacts are breeding but I can ask around.
