It's unfortunate to see that the product uses animal-based foods, and eggs at that. Something like Soylent should in my opinion be vegan (for the environment and the animals). If I recall correctly, Soylent was pretty close to vegan.
I mean, simple respectable pain-management could help with de-beaking, but the existence of unwanted male birds is a hard problem.
I'd be a lot more comfortable with ovo/lacto vegetarianism (which is what I do) if those problems could be solved, and I'm no luddite - if there was a high-tech solution to these problems using crazy cloning techniques or somehow inducing parthenogenesis or something, that would be great.
