Biggest falling livestock threat today was sheep. There was even a black one. They seemed intent on falling down the giant hole. I don’t know if that’s typical for Earth sheep or if it’s something peculiar to these sheep. I do know that even in lower G I don’t really want a sheep falling on my head. The cow was traumatic enough.
So grading the area outside the hole is making more and more sense because it lowers the chances of sheep crashing through my makeshift fences and falling into the hole and rotting in the rainwater pond at the bottom.
In this place, that would probably cause some other murderous creature to evolve.
