Egg Market Disrupted in U.S. as Cages Made Roomier

Eggs are about to get more expensive, as California moves to make sure hen houses are roomy enough to allow the birds to lay down, stand up, extend their wings and dance around.

Farmers nationwide who want to continue selling to the most populous U.S. state are moving to comply with a new law, taking effect next month, that requires the larger cages. They either must build more hen houses, or house fewer birds in the ones they have, raising their costs.
