A few days ago, I posted a couple of pictures of me dumping in bins full of grass clippings and leaves into the chicken run. The chickens will scratch and peck that litter over and over again until it breaks down into compost.
I mentioned that I save a lot of money by making my own compost instead of buying bags at our big box stores. Yesterday, I harvested about 14 cubic feet of finished compost in less than 30 minutes of work using my cement mixer compost sifter. I wondered what the current cost of compost was at Menards, for example, if I had bought it there. This is what I found online...
I checked the math on that and found that if I would have bought 14 cubic feet of that compost at Menards, it would have cost me over $79.00 with the price after rebate!
I only sifted out 2 wagons full of finished compost yesterday to top off a number of Dear Wife's planters and one of my raised food beds that I pulled the tomato plants.
Here is a picture of the newest planter I made out of pallet wood for Dear Wife's "wild" flower garden. She had a couple of plants that were being stunted by some other plants that overgrew an area and she want them moved before they died...
I call my homemade chicken run compost "black gold compost" because it is so rich and black, and it saves me so much money by making it at home.

For many years, I used a simple 2X4 frame with hardware cloth tacked on to the bottom of it to sift my compost into a wheelbarrow. That worked great, except that it was a labor intense operation that took me a long time. But I would spend hours sifting compost from my compost bins at that time and end up with half a wagon of finished compost. As I got older, I wanted a better option that was labor saving.
I invested in making a cement mixer composter sifter shortly after deciding to convert my entire chicken run into a chicken run composting system. At that time, it cost me about $240 for everything, but that was because I had to pay for a new cement mixer which was on sale for about $200.00. I could not find any used cement mixers for sale in my area. That would have saved me a lot of money and worked just as well.
In any case, given the price of bagged compost at that time, I calculated that my investment had a break-even point of 4 hours of run time because I was able to process $60.00 worth of sifted compost every hour. With today's compost prices, I calculate that I am making finished compost around $150.00 per hour!
Here is a picture of my current setup with the cement mixer compost sifter...
It's one of the few investments that I have made that has paid for itself so fast. The best thing, for me, was that it saves me so much labor and wear and tear on my old body. I don't know how to calculate that benefit, but not having a sore back at the end of the day is pretty valuable to me.
