Do all penguins lay eggs?

VL Dude asks:

I’m pretty sure that penguins lay eggs. I believe that the reason is that they are actually birds not mammals. Please confirm. Thank you.

Yes, penguins do lay eggs. Emperor or King penguins will only lay a single egg. All other types of penguins, from the Macaroni to the Galapagos, lay two eggs. Penguins are not mammals.
