Okay, I can complain that a neighbor has a purple house (trim) and several others drive golf carts. Oh, and the guy down the street has a large garden with corn. Just because I complain about something, doesn't mean that my complaint trumps their rights, or that it has any legal standing. (For the record, none of these things bother me--just listed as examples.)

IFF (mathematical If and Only If) there is an ordinance prohibiting chickens in a residential zone, and that is your zone, she may have a legitimate complaint. However, since they have not provided you with a specific ordinance that you are violating, TOUGH.
She sounds a bit bizarre, and you need to make sure the PO charges her for mail theft or interference. You may want to request that the PO hold your mail and pick it up at the PO if you cannot trust her to keep her hands off. Or get a locking mail box. I agree, do not make personal contact--she could be dangerous.
