Eggs

I enjoy eating eggs: scrambled, boiled, omellettes, etc it doesn't matter. But I've only eaten chicken eggs.

I've always wanted to try ostrich or even emu eggs. But this got me to thinking, how different do eggs from different species of animals taste?

Are quail eggs vastly different from duck eggs in taste? Has anyone eaten any of these?

Also, would anyone be willing to try alligator eggs, crocodile eggs, snake eggs or even platypus eggs? If you have, can you tell me about the experience?
