I'm lucky in that I live out in unincorporated Granville County (just a bit north of Raleigh). The only rules I've got is a) I can't have a hog operation, and b) I can't build a trailer park on my property. Anything else goes!
Just about got my chicken tractor done, waiting on my friend who's going to order 25 chickens and I'll order 3-4. (Will post up more when it actually happens, ha ha!)
I think (hope!) the trend will start changing.
