In one of my recent D&D sessions, one of the members of the party (rogue) tamed a wild turkey. Since then, the rest of us have wanted a companion/pet as well (ex: Blood Hawk, Bat, etc.). Are there certain rules for animal-taming? Or is it completely up to the DM? Because with the turkey, they tamed it in one roll.
Please note that none of us are Rangers or beast-masters.
And we are playing in Adventurers League (the DM usually decides whether to use a rule or not).
