Cage free eggs won't be cheap

Right now, the US market has about 300 million laying hens, and only about eight percent of them are cage-free, according to this story in Wired.

 
In 2014, the US as a whole produced nearly 100 billion eggs, totaling $10.2 billion in revenue. This kind of mass production depends on cages. With those tiny wire boxes, farmers can micromanage everything about a bird’s life. They can even help automate egg collection by forcing the bird to lay its eggs directly into a funnel that drops down into a collection area.

Today, eggs are widely available and cheap mostly because of caging systems.
