The price of eggs and supply and demand

I have never understood the law of supply and demand. Whenever there is a shortage, the item starts costing more? Today we have a short supply of eggs; $1.78 for dozen eggs is now $6 or more. Did chicken feed, and transportation suddenly increase by 300%? I don't think so.

There must be some mathematical formula beyond a third-grade level that drives the prices skyward. An item is in short supply. production costs remain the same, but now is the time to jack up the price. I think someone is making too much money. 

Why heck? I've become a long-time old-timer and there are fewer of us each year; as we diminish in numbers, I wish we could become more valuable. But then, I guess there's not much demand for old codgers that walk with a limp.
