The answer to that question will depend on who it is answering it. Nothing on the farm is high enough when you consider the production costs. Even that 125 dollar bale of hay only brought 35-40 to the farmer if he was in Missouri and it was shipped to Texas. You can figure every detail of cost but in anything to do with farming, it will not add up to making money when you do that. Nowhere in farming is production cost figured into what you receive, unless you have built a business where you deal straight with the consumer and they will pay whatever you ask---some sort of specialty market.
The value of hay is totally dependent on what someone is willing to pay for it.
As for myself, 25 dollars for a 4x6 of good grass hay is what I can afford to pay for hay to feed to cows that I buy, to winter and resell. Higher than that, I have to skip buying cows. 35 dollars for the 4x6 is what I can afford to buy to keep my permanent cows. Those are my values for hay.
I had planned on buying alot of cows this fall, so in March, I bought about 1200 bales of hay for 15-25 dollars per bale. In June and July, I paid 35 for 900 more for my permanent cows. Now, with no rain since late May, and feeding 10 bales per day, right now, not only will there be no buying of cows, there will also be selling about 100 springer cows in a couple of weeks and sold 110 head of calves 60 days early last week, just to have enough to get through the winter. If we still do not get any rain in the next 2 weeks, that means another 50 cows go to town.
There is all the talk of 2000 dollar cows next spring, and I hope they are. The last time this happened was in 1980 and cows were going to be sky high "next spring". Spring came and you could buy the top cow-calf pairs for 300 dollars per pair. So, I am not going to borrow and bet the farm by trying to keep the cows, ever again.
So, is hay too high at 70-125 dollars per bale? To me it is.
