I wish you the best of luck in your meeting today. But keep in mind. The inspector may be wrong or thought the ordinance stated something it did not.. I had a case a few years ago where an inspector cited me for not having a fence around my pool. The ordinance said as long as the pool was higher than 48 inches no fence is required. He misread the ordinance and stated that it said any pool must have a fence around it. I took the ordinance in and sat down with the enforcement officer and the zoning department and proved I had a 52 inch high pool and therefore it did not require a fence. Go with an open mind and try to work with them. Take pictures of the coop, run and the chickens and show them they are pets and not some agricultural business. You may have to make them house chickens!?!? Guns blazing attitude as a last resort only.
