The age old saying "If you want respect, you must give respect.".. in other words, it's best to be calm and civil about everything and ot will get you farther. Keep it peaceful. It is very important, before acquiring any animals, to go directly to city hall and ask for copies of any ordinances pertaining to whatever you plan on getting or doing. Doing this would have prevented any issues now. Don't be to frustrated with the city, as they are only doing their jobs. If they conducted a field inspection, it was brought to their attention through complaints first. Again, they're only doing their jobs. Request the copies of the ordinances and request a meeting to see if they will work with you or what you need to do to avoid violations of the ordinances. If they say strict dimensions, your best bet is to downsize to those dimensions. Are the number of ducks also the problem? Their enclosures? Their being? Its not right to justify breaking the law on our mental illnesses. I whole heartedly understand you love your ducks and they very well may be your emotional support, but that still doesn't mean you are in the wrong here and that the city has every justifiable right to take action. 9 times out of 10 though they will work with you in a civil manor to satisfy both parties, if done so politely.
