Some Button Quail will have a panic attack if a fly buzzes through their cage. lol
But, they do get calmer as they get accustomed to certain noises and interaction.
I can reach into a cage and retrieve eggs and as long as my motions are slow and I tell
them I'm only collecting eggs they're fine with it. It wasn't always that way though.
They used to skits out at opening the door.
Unless it was a REAL close lightening strike where the Boom accompanies the flash they should be ok.
