I don't know what Michigan's laws are or codes for sale but some states require certs of testing or have chickens testing available at the swap/fair. Look into what's offered at the farmers market, ask the seller questions as to if flock is disease tested and how often. It could be a good and safe way to go.
But sex links from the local feed store is also an awesome way to start out. Will be great layers, hearty and guaranteed females. I'm partial to the black sex link from back when we got our first flock from a feed store. Huge eggs and was my best layer, very friendly too.
