ok, since people here are awful, i will tell you how to use the dodo egg.

there are 3 ways you can use the dodo egg. you can wait for it to hatch into a baby dodo, you can use it to tame pteranodons, icthyosaurs, or mesopithicus, or you can make dodo kibble.

the recipe for dodo kibble is dodo egg, rockarrot, cooked meat, mejoberry, fiber, and water in a cooking pot. start the fire in the cooking pot and after 30 seconds you should have some nice fresh dodo kibble to feed your dodoes.
