@BReeder! It sounds like you have done about all you can do.
I had a huge pile of old hay, leaves and coop cleanings that sat out all winter one year. the pile was about 6 feet high and probably 10 feet in diameter at the ground. The outer foot of the pile was mostly frozen, but the inside composted along all winter. I turned it in spring and tried to put the outside stuff into the center of the new pile and it was mostly composted about 2 months later, so ready by early summer.
I am just north of Green Bay, so cold - snowy winters here.
