I have heard others on this site fight their case through knowledge. Take lots of photos and explain your set up and proximity to neighbors. You could even take a poll and opinions from the neighbors in your area to voice their two cents. On this site people have worked on a pamphlet. https://www.backyardchickens.com/forum/viewtopic.php?id=184640 and http://www.bellecitychickens.org/index.php/Main_Page The more informed people are could help. Lay out a case for them as exotic birds and pets. More information for us would help. How many do you have? Size of the coop? Size of your property and how close are your neighbors/road? Hope this helps
