Dodos are almost completely useless, but they are great for beginners to get the hang of things. Even if you know this right from the start, a dodo is probably one of the best first tames if you just want a companion to take along. Oh yeah, and they can mate and make eggs, which I'm pretty sure makes food (if you don't hatch it that is).
More Dodo Utility Tips
You can get prime meat from the babies, but it spoils very quick, so this is how to get it all to a predator:
1. Incubate lots of dodo eggs so they only have one or two seconds left to hatch.
2. Carry the dodo eggs as well as a campfire (you might need two) and fuel.
3. When you’ve knocked out the predator you want, light the fire and hatch some of the dodo eggs.
4. Kill the babies and harvest their meat with a metal pick.
5. Feed the meat to the predator and enjoy!
I’ve experimented, and it looks like you get two to six prime per dodo.
Dodo's have a chance to lay an egg every time they poop. So force-feed them a bunch of stimberries (That will make them poop, and lay eggs)! Just make sure that you have some regular berries because it will make their food go down. Never again will you have to worry about obtaining Dodo eggs. You will only need to tame one!
