If most farmers agree, and don't do this, then why is it that you ignore the Constitutional issue and rant on about chicken comforts? Why should the entire nation be subject to one state's laws when they are based on a notion that you already assert is mostly untrue? If most farmers don't do this, then why must 300 million people face higher prices to address an issue that only concerns a few farms and have it dictated by only one state?
I willingly pay higher prices for fresh eggs from local farms. Don't need any laws in place for that - it's a consumer choice. If others want to eat cheap eggs from chickens that are cooped up in cages all their lives, that's up to them.
