Fire Ant Farm
Get off my lawn
Yes they can. All it takes is one hen to get the whole chorus going. I suspect that is their nature in the wild like a deer snort gets the whole herd moving.
Well, it only takes one time for that to be due to a real predator/threat for it to be evolutionarily beneficial...
I have a few different groups - Naked Neck, Cream Legbar, and Speckled Sussex (with a NN rooster). The Cream Legbars are less cuddly, so to speak (though not outright antisocial), but have a lot more common sense - they know to hide or take cover immediately at the threat of a hawk (common here), while I find myself yelling "get under cover you fools" sometimes to the others. As long as it doesn't interfere with my ability to care for them, I'll take more alert birds any day.

If I want a puppy, I'll get a puppy. (Though, now that you mention it, I actually have a Naked Neck pullet named "Puppy" who knows her name and comes running when I call her and then begs to be picked up...)
(BTW, I'm not sure if I posted this, but I was following your NPIP odyssey. Belated congratulations!)
