legalize my chickens

Norman just like many other cities have a strict policy about the keeping of animals other than dogs and cats. Mainly, these restrictions keep home owners from raising farm animals such as chicken or rabbits by demanding a large distance between your home and the chickens home. In norman that distance is currently 100ft. This distance requirement allows 10% of the norman population to legally raise chickens. The other 90% may not. it seems that this distance was established because of some sort of health risk that may arise f chickens are in too close of contact with humans. Strangely, large cities like Seattle, San francisco and even Oklahoma city have a smaller distance requirement. So, in areas which higher human densities the raising of chickens is allowed in a smaller proximity. does this seem counterintuitive to you? So here in Norman, 90% of the population is barred from raising chickens for what reason?  

its time that this silly city ordinance is changed and the people are returned their freedom to raise their own food.
