Personally, I'm kind of conflicted on this issue.

On the one hand... I really don't like the type of ranching that exists in places like California.  Specifically, the close confinement of animals to one another (and chicken farms are the #1 culprit on this) are breeding grounds for mutating flu viruses.  Remember bird flu?  Yeah... Chinese concentrated chicken farms...  This is an externality current farming doesn't take into account, and may actually be inhibited in some cases.

That being said, how would such a bill actually affect the industry?  Yeah, it would increase the cost of operation.  However, what beneficial activities would result?  I couldn't venture a guess, but because non-concentrated animal operations don't use cages in the first place, it may be possible that this would give non-concentrated animal farms a leg up against concentrated farms (one thing to remember... concentrated animal feeding operations get a ton of subsidies, both in the form of direct subsidies to pay for capital resources and cleanup efforts, and indirect subsidies in the form of subsidized corn and other crops which are used for feeding the animals).

Yeah, I like stuff that gives these farms a hard time (personally, I think we need to remove the subsidies, requiring the animal farms to legitimately compete with non-concentrated farms).  That being said, given my concerns, this isn't much of a direct address to those concerns (it's obviously primarily intended to fight animal rights abuses, obviously).  It definitely could give the farms a hard time...

just put wires into their brains that make them think they're living in an awesome chicken city
