have you looked to see if the town ordinance or statute has any provisions for "waivers"? Are you presenting signatures from as many neighbors as possible? And personally I wouldn't discuss all the things you didn't do because.....if they remove the rooster I would let loose and do those things you want to do. It might be good also to find out if the board has ever done anything EXCEPT enforce the ordinance. They may have no choice, but if they have ever made exceptions....thats your ticket.
good luck!
