I'm not huge or athletic but I probably weigh, like, twice as much as a goose. I get that they're incredibly pissy and they have teeth and pointy bits, but I'm still betting on me.
In this context I think we have to assume life or death tactics by both combatants.
But that’s an important distinction because MOST of the time we deal with pissed off animals that we don’t want to hurt, much less kill. So that gives some animals a big advantage in real world encounters. Maybe most adults could kill a goose if they had to, but in real life 99% of adults are going to back off or run away rather than deal with a fucking goose!
Punt to the chest. Bird bones are papier mâché. Never get in a fist fight with a goose, their wings will break your arms. Definitely don't try and snap its spindly little neck. Just kick it in the chest
