Hey everybody -
Just followed up on another MRTFA thread, and found another relevant document, this one written by Tim Fischer, Deputy Policy Director for the Michigan Environmental Council, in 2009:
http://www.michiganbees.org/wp-content/uploads/2010/03/RTFA-Beekeeping-SEMBA.pdf
The specific topic here is beekeeping, but the arguments about the kind of protection afforded by MRTFA are the same for chickens. This is another really easy explanation of MRTFA, prepared by a respected organization, that might help skeptical officials understand that MRTFA really does protect the rights of people to have chickens (or bees) so long as they meet three requirements:
1. Are a farm operation (have chickens, for example, or bees)
2. Are commercial (sell eggs, for example, or birds, feathers, or compost)
3. Comply with GAMMPS (are clean and responsible)
There are more details, of course, but none that are not easily met. I would hand a copy of that document and the one posted earlier from MSU to city officials, and ask them to explain what part of the law permits them to enforce local ordinances on you if you meet those state requirements.
Best of luck to both of you, CaraBear and jphillips.
OK, just for grins, here is that other MSU document one more time:
