What was the reason for the violation? I'm going to guess noise or chickens not confined, since it appears it is legal to keep them in Royal Oak?
I didn't see anything about a permit being required, either, but the city offices should be able to tell you if you need one.
Here's a link to your code.

I found this on another site:
http://urbanchickens.org/we-need-your-chicken-ordinances
City of Royal Oak Michigan allows chickens:
Must not be allowed to roam "free range" unconfined. Pens/coops must be clean.
No excessive noise.
No limits on hens or roosters.

Application for such permit shall be made to the City Clerk upon blanks furnished for the purpose. Such application shall state the location where such livestock or other animal is to be kept and describe the conditions under which the same shall be kept. Such permit shall be granted by the City Commission only after investigation and recommendation by the Chief Inspector. No permit shall be issued for the keeping of any such livestock or animal except where it appears that the keeping of such livestock or animals is not likely to create a public nuisance. If at any time it appears that the keeping of any such livestock or animals creates a public nuisance, the City Manager, Health Officer or Chief Inspector may, whether or not a permit has been issued, order the owner or keeper to abate the nuisance or remove such livestock or animals from the City, and if he fails to do so within seven days after he has been served with said notice, the City Manager, Health Officer or Chief Inspector may summarily remove said animals and abate said nuisance.

No stable shall be maintained without concrete floor draining to a sump of a style and character approved by the Building Department with a drain connection to the sewer. Said concrete floors shall be completely flushed and washed at least once each day. Every stable shall have a complete set of screens on all openings for ventilation, or ingress or egress, so that insects may be excluded therefrom. Such screens shall be kept closed at all times except when opened for purposes of ingress or egress.
