Hard to say. It's definitely animal, no doubt about that. I mean, it's an unfertilized bird embryo, like saying it's pre-bird. But then again, it's not the actual flesh of an animal.... or is it?? I mean, it's the flesh of an unfertilized bird embryo, it's what flesh as we know it develops from, yes? It's animal, pure and simple.
However, strictly speaking, because it's not fully developed into the flesh that we know as flesh, it's not considered to be meat.
EDIT: It may not be fertilized, so it's not the end of the egg's life. However, it does come from cruelty, because the hen's life is a living helllllllllllll. She's cramped, with as much space for herself as one sheet of notebook paper. She can't spread even one wing, and the "floor" she stands on is wire, so her feet get cut and infected. Her food is dirty, so is her water, even has poop in it. Her air quality is HORRID, full of urine and fecal dust, and causes lung diseases. Also, the air is so full of urine that even her skin gets irritated and raw. She has no quiet time, no space, no place to even scratch the ground or take dust baths, things which she naturally does, things that are instinct to her. Her life is a living hell.
I would never eat eggs.
