I'm doing my first compost piles, as well.
Couple of things; Those piles of horse manure from stables are not very high in nitrogen (greens). I found this out when the master gardener advising the community garden I'm involve with had us start a pile with brown leaves and manure from a stable. It wouldn't heat up. I confirm this with the person involved in Florida's Sarasota community garden. They handle 30 tons of raw material annually for the numerous gardens in their area and run the Florida Online Composting Center website ( https://sarasota.ifas.ufl.edu/compost-info/
) They found they needed to treat stable waste as high carbon (browns) and ramp up the nitrogen to balance. And their advice to get that pile going? Load it up with coffee grounds!
Second, USDA Organic standards for composting requires you to get the compost above 130F and then turn a minimum of five times in 2 weeks while maintaining temperature above 130. I'm recalling this from memory, so I may have it a little distorted, but they expect hot composting to require frequent turning. This mainly to breakdown potential pathogens in the manures (I think).
I'm thinking turning 4-5 days while it's hot may work well. I've turned my leaf and coffee pile at home (five foot diameter pile that 3 1/2 feet high) four times. The first 7 days after it got to 130F and stayed there at 130F all that time. After turning, which allow me to see the center was getting very dry and allowed rewetting, the temperature started at about 100-110F and then climbed to 140F and stablized for 5 days. Day 6 and 7 temperature edged down to 136, and I turned the pile again. Shot back to 140 in two days, so I turned on day 6. After a couple of days pile was back up to 140F and then climbed to 151F! That was 5 days ago, and I want to turn this monster tomorrow, if I can.
The center has been getting progressively richer in color and texture. With frequent turning, you'll get a good idea of the moisture content of the pile and bring more oxygen into the mix to keep the bacteria happy and growing. Sounds like a no-brainer if you have a big pile and got hot composting going to turn that thing often.
