Tame using prime meat or mutton. Torpor drains somewhat quickly. Recommended to kill at least 5 jellyfish before hand so you can get enough biotoxin to keep it sleeping. Good luck, and have fun on ark.
From what I have heard you can breed dodos to be so big you can ride without saddle, or you can breed so small it can sit on your shoulder. Working on breeding them big. To breed small/big then just breed your biggest/smallest dodos together. Hope this helps. if helpful 👆, if unhelpful 👇
