To my knowledge the recommendations are the same regardless of region and are as follows from the Michigan Department of Natural Resources: 

"Yes, you may use backyard bird feeders. Regular cleaning of bird feeders with a 10% bleach to water solution is always a good practice to avoid transmission of HPAI and other diseases more commonly spread at bird feeders. If you own domestic poultry or have a backyard flock, it is recommended that you do not feed wild birds."

You can also find county record updates here: https://www.michigan.gov/dnr/managing-resources/wildlife/wildlife-disease/disease-monitoring/avian-influenza-updates

There is currently one positive case in Washtenaw County and one positive case in Jackson County.

I hope this helps.
