Another thing just popped in my head, when ordinances are being debated, the same comment seems to be made: chickens bring predators into the area: raccoons, skunks, weasels, rats, etc.
Obviously, you wouldn’t write this in your letter but I would at least think of a statement or rebuttal if...
I agree that 8-12 chickens is a huge number for that size of a lot. Most prefab coops can only house about 3 full grown chickens (prefab coops also over exaggerate what coops can house, their number they advertise should at least be cut in half)
Roosters crow 24/7/365 not just at dusk or dawn...
