Thank you for the heads up! Here's what I found on zoning for future questions -
Section 5.12.040 Farm animals, livestock -- Restrictions on keeping, etc.
1.The raising and keeping of farm animals is hereby prohibited except: As permitted in the zoning ordinances of the City; at zoos; at schools, clinics or laboratories for recognized educational, scientific or research purposes; providing the keeping of them does not create a public health or safety problem.
2.A person may not keep or raise domestic fowl, livestock or non-traditional livestock, within the City of Dickinson except as permitted in property which is zoned as Residential Agricultural - "RA" or Rural Residential - "RR", as defined by zoning ordinances. Domestic fowl when kept as permitted may not be kept within 150 feet of any dwelling unit other than that of the owner of such fowl. All fowl must be kept within a secure enclosure and it is unlawful to allow confinement areas of fowl to cause unpleasant odors, or to permit fowl to create noise or attract vermin which may affect the health and well being of persons living nearby. The restrictions concerning where fowl may be kept do not apply to young domestic fowl being kept temporarily in business places for sale.
3.It is unlawful to keep animals or fowl in the city which have been bred or trained for fighting for sport or exhibition.
4.It is permitted to display farm animals in parades approved by the city. (Ord. No. 857, §1; Ord. No. 1131 § 3; Ord. No. 1332 § 24.)
Section 5.12.080 What constitutes nuisance; nuisances prohibited
