Sorry to keep doing this, but I didn't want this to get lost... I know it's important to ChickenLover...
§ 160-33.1. Right to farm; permitted use in designated zones. [Added 9-5-2000 by Ord. No. 30-8-2000] A. The right to farm, as defined in N.J.S.A. 4:1C-3, is hereby recognized to exist in the Township of Evesham, in the County of Burlington, and is hereby declared a permitted use in all zones of this Township, where an agricultural use is preexisting and current, and a permitted use in the following zones under any circumstances: Forest Agriculture (FA), Forest Woodland (FW), Rural Development-1 (RD-1), Rural Development-2 (RD-2), Rural Development-3 (RD-3), Regional Growth-1 (RG-1), Regional Growth-2 (RG-2), Environmental Protection (EP), Low Density (LD), Medium Density (MD), and Affordable Housing (AH-1, AH-1A, AH-2).
This right to farm includes, but not by way of limitation:
(1) Production of agricultural and horticultural crops, trees and forest products, livestock and poultry and other commodities as described in the Standard Industrial Classification for agriculture, forestry, fishing and lawful, humane trapping.
There's more to it, distance of coop from the lot line and such, but look here, and search from there.

Also here...
http://www.e-codes.generalcode.com/codebook_frameset.asp?t=tc&p=0481-160.htm&cn=1184&n=[1][951] and do a search on this page for poultry. there's more details to it, that right to farm stuff has limits. and the zoning specifically says poultry are NOT considered pets.
Here is your county extension office info too, in case you want to talk to them anyway.
