Apparently horses sometimes eat small birds. They shouldn’t but it seems it can happen if they are hungry, or bored and/or curious.
Imagine being bored and just like “oops I ate this living thing that was screeching trying to escape”
Well, i usually open the fridge out of boredom and casually give a bite to a dead chicken that is stored there… either that or take a slice of a monolith of emulsionated pigs.
