I agree. I would expect to see my chickens start their lazy wander to the coop as they do each day as soon as the shadows hit the lawn.This is hilariously incorrect. There is no abrupt change in light. Eclipses last an hour or more. Even at totality, it's dusk. Not pitch blackness. Most animals don't care at all. They're not looking up at the sky wondering why the lights went out. Do they freak out at sunrise or sunset? Those behaviors are what you can expect to see.
