I think a state has a right not to accept a product from another state. Animal rights is a serious issue. And that includes chickens.
I think that a smart chicken company would use larger cages, and advertise how it "cares" about it's chickens, and make people go "awww".
FogHorn LegHorn was not just a chicken
Bugs Bunny was not just a rabbit
Charlotte was not just a spider
Mighty mouse was not just a rodent
Were these small cage keepers kids once? Did they not get attached to these animal stars?
If larger cages mean less profit, it should have never been done to begin with.
What if a state decides that all products imported to that state must be produced by white people ?
