Looked it up a while ago. You can hatch/care for chickens in South Orange (think school project), but after a certain age (maybe 6 to 8 months), you are no longer able to keep them. The Village didn't always have a prohibition against "fowl".
Had a neighbor who kept a couple of big parrots and a cage of guinea hens out back that sometimes roamed (I'm sure they kept down the ticks in the wooded areas behind the yards). Never a problem.
If you want to keep them (I'm saying maybe 2 to 4 hens max), petition the Village or find a friendly Trustee to help change the ordinance. You won't be able to keep Roosters (they crow) and would have to keep them in a pen and as clean as pets you would have in your house.
Believe it or not many years ago chickens were allowed in SO. There were a number of Italian people living on Church St.They had wonderful vegetable gardens and chickens. You could buy a fresh-killed chicken,so fresh that you could see it happen. There was the headless chicken running around the yard, An alarming sight for a child(me).
Does anyone know if it is legal to raise backyard chickens for eggs in south orange? Thanks!
