I know that feeling.
Well, not exactly, because I free-range, so they get lost a lot more, but still. The stupidity comes through, nonetheless.
Chickens don't always have a whole lot between their ear-holes, either.
Guineas, though... they scream and scream and scream until they feel that they have scolded the air enough... and they tend to not feel that way for a while.
I just have never had a flock that couldn't figure out how to get back in the coop at night. And herding chickens is a real pain in the butt!
