You are right of course, but I found what you said to be true of any farming operation, not just hay.
One way I found a farmer can get ahead is to build your own equipment, and think outside the box.
For me, I hay on the shares, which is, a guy with haying equipment comes in and hays my fields, and I get half of the hay. I would rather do it myself, BUT I cannot beat the price. I get hay for free basically. And that would work for anyone, as long as they have twice as many acres as they need.
But if I had to put up my own feed, I would never go with hay. I have sheep, and they thrive on silage. The average person also has the equipment already to process corn, and if they grow a garden, to plant corn as well. At 24 tons to the acre, they could really cut down on their feed costs. In the past I have fed my sheep with corn, cutting the corn down with a chainsaw, and then chipping it in a Troybilt Tomahawk Woodchipper. The result was corn silage that was identical to the silage that came out of our 1/4 million dollar silage chopper. But I used a woodchipper because I had it, a person could also cut a hole in top of a push lawnmower and run their corn stalks through that to produce silage.
If that is too labor intensive, a person could mow their field with any type of mower, then after it has wilted down to get the moisture content down to 60 percent, take a flail chopper and blow that into a wagon, and then form a nice pile and cover like any other silage pile. That would be a lot easier then using a hay baler because you would not have to have 4 days of good weather, and plastic sheeting is a lot cheaper then putting hay in a dedicated barn. That is what I would do if I did not have free hay.
