People who don't give much of a shit about chickens continue to buy cheap eggs. You've created a non-problem that takes place in an alternate reality, and then got upset by it.

Intelligence isn't the only metric we use to care about animals. Pigs are more intelligent than dogs, so what? I'll eat a pig, but I'm sure as hell not comfortable eating a dog.

I'm not a vegetarian, but I can't see anything wrong with wanting a world where the animals we eat aren't put through suffering. And yeah, there's lots of things that I'd like to see improved (e.g accessible health care), this is just one of many things we as a society can try to improve.
