So, how did they do?
My chickens were caught off guard in the woods when totality hit. They got real quiet and started moving cautiously as a big group towards the coop. When they were almost to the coop totality lifted, and they were left looking about as confused and foolish as chickens can look. It's almost like they didn't trust their senses, because they took a moment to eyeball the area before getting back to their routine.
I also have guineas, geese, and muskovies. They all got quiet and hunkered down where ever they were. The geese and ducks were very still, had their heads tilted and were looking upwards. I think they were watching all the bats emerging from the trees, but I'm tempted to pretend they were joining me in looking at the sudden hole in the sky.
