Since this is generally a first breed for new players, I’ll put this here: to hatch an egg, drop it near a fire pit. Once it hatches, you need to claim it, or it will die. After doing so, add berries to its inventory and manually feed them till about 10% maturity. After that, they can eat on their own.
For the guy who said that it would be cool if a dodo could sit on your shoulder: on ark mobile, a dodo smaller than .75 can in fact be carried on your shoulder. Dodos over 2.6 can be ridden. Fun fact. :)
On mobile these can be bred to get insane sizes, like huge, bigger than an Allosaurus and they have 8 abilities unlocked at certain sizes. I only know 2 abilities, one is the dodo gains an immense amount of speed and charges towards the target. The other that I know of is that it jumps up and slams into the ground which stuns surrounding enemies. Do not underestimate the potential that these have on mobile, they can become beasts.
If you have to pick up a dodo(a very early tame, likely your first), choose a female. Dodo eggs are able to be made into basic kibble/dodo kibble(depends on the playing platform), which can be used to tame some powerful early tames.
