No, that's not how it works. You've provided a chart that shows average prices for a specific point in time. That's it. They are constantly fluctuating, and the price is based on supply and demand.
You don't get to charge 3x for an egg just because it's 3x the size. I mean, you can try, but people will not buy it unless that's the equilibrium price. There is no rule stating that price must increase by the same amount as the size of the thing. That's silly.
A thing is worth what people are willing to pay for it. Goose eggs simply aren't as popular as chicken eggs, therefore the demand is lower. Assuming supply remains stable, that means price goes down.
