I think one thing the OP needs to do is verify that there are no other ordinances or zoning that specifically relate to animals.
There is a point, as was mentioned, to having the wording vague and broad, as it allows the ordinance to govern a wide variety of situations that might arise in the future. On the other hand, if the wording is TOO board or vague, it becomes meaningless--can be interpreted in far too many ways. I believe this particular wording falls a bit too much into the too vague category. It does not define the amount of dust or odor that is prohibited. If one lined one's property with well-maintained rose bushes that had been selected for strong and lovely fragfrance, one would be violating the letter of the ordinance by placing an odor producing substance within 100' of the property line. For that matter, any property that is not larger than 100x100 cannot even have a rose bush, or jasmine or lilac or any other fragrant plants. Likewise for plowing or rototilling a garden.
I am pretty sure that those uses were not envisioned by the writers of that code, but, rather that they were thinking of things such as pig wallows or feed lots or other unpleasant odors produced by concentrated animals kept in less than ideal housing.
Healthy chickens kept in clean and dry housing do not have any significant odor. I have a fairly strong sense of smell.
Having an attorney review the wording and asking how it pertains to what is wanted (a dozen chickens, 3 layer hens, 50 meat birds, etc.) seems like a wise choice. Quite frankly, more and more CITIES across the country are deliberately making changes to their ordinances to allow various numbers of hens for family use or pets. It is difficult to argue and 3 hens are an agricultural use when many cities define that number as pets or for family use.
