OMG.......... now that you mentioned your critters........
I looked out at my hens about that time and saw that 4 of the 6 were standing up against the coop with their heads tucked under their wings.
The other 2 were walking back and forth across their “run”, rapidly.
I thought it was hilarious but now come to think about it, I remember looking at the clock on the stove and IIRC about 4:03 pm.
Maybe that is what those hens were doing ?????? feeling the quake ~?
Makes sense to me. My animals were really acting up a half prior to and after.
