Composting manure/mortalities

For 2 years now, I have been composting bedding pack and mortalities. It’s been a learning curve but a worthwhile one nonetheless. Stirring the windrows is the thing I struggle with in a timely manner. Anyone using a windrow turner for composting? I have a cousin who works for U of M research center in Waseca MN, said there are only a handful of people in MN doing composting. More readily used in hogs but they don’t do the manure, just the mortalities. I guess I’m just looking for anyone else
composting?
