It results in less meat consumed, so it's better for the environment, etc. A bit of egg vs. a lot more meat. And chickens produce a lot more egg than they do meat if you're raising then for eggs, so it's better. Not perfect, but better.

If you went for perfection, you'd never use any form of motorized transport, never eat any foods shipped across state lines, set your thermostat for survival temperatures, and go full "freegan" for everything you consume. There's a point at which better is all you really can do - just how much better is the question.
