Even in good times we have only been just over 50 days away from running out of grain globally. Extreme weather, ethanol plants, growing meat consumption in developing nations. Livestock worldwide consume most of the grain, but we are always just a few bad crop years away from shortages.World wide crop failures this year. Usually it may be one spot or another, but grain staples have been heavily damaged all over the world through various crap circumstances. https://news.mongabay.com/2021/08/a...ate-disasters-raise-alarm-over-food-security/
Economic destruction due to govt mandates is behind many of the shortages already. Inflation due to central bank money creation and interest rate suppression is driving capital to seek gains by speculating in grain and soybean futures. This distorts supply and demand until prices no longer mean what they should. Credit and petroleum supplies are critical to our grain based global food supply and this is where the real threat lies. A credit bubble about to pop and govt interference in energy make for a potential catastrophe. Rather than wait for shortages to arrive, I choose to manage my flock in such a way as to be more resilient. If we are lucky higher prices will be the least of our problems. If governments try to control grain prices or subsidize grain production this will make the situation even worse. Forcing people to burn grain based ethanol in their vehicles is making things worse. Governments living beyond their means and pretending to be Santa Claus is making things worse. Protect yourself because they will not.
