Can't the... feed them to poor snakes in China, that can't afford a good meal?
I doubt there are enough snakes to dispose of all of them, and that doesn't seem like much of a favor to the chick anyway.
As the reddit thread pointed out, it is actually quick and painless vs. what some places have been known to do--things like just throw them into giant garbage bags until they eventually die slowly from being crushed, suffocation, or heat stroke. And it's not like they're being wasted. That gore will almost certainly be recycled by being added to some kind of animal food, maybe even chicken feed.
