My favorite thing to do with dodos is to gather about 40-50 of them, stick em in a walled off area with no roof, get my pteranodon, and kidnap naked to drop them into a pit of ravenous aggressive dodos ;)
Me and my friends once had a dodo farm and we were choosing some dodos they chose one but I secretly got another named Felix and hides him in a little house I made for him then raptors came and attacked him I was so sad I got another dodo and named it Felix jr and made a more protected house for him and made a grave for Felix the first.
if u are new to ark then yes u can tame one or two but don't let ot get tooo much. i know they are cute but that's it. they are not helpful and u need to take care of them. i had so much of them and it broke my heart to kill them because i couldn't tame more dinosaurs
