Chickens and ducks seem to deal with the world in different ways. We currently have a group of ducklings and a group of chicks, all roughly the same age. They also share a penchant for escaping from their nursery cages when they're hungry, thirsty, bored or none of the above. When a duckling makes a break for it, it pops out of the cage and plummets off of the table down to the floor with a kinda wet thud. It then proceeds to run around in circles just underneath the cage, until someone finds it, puts it back and corrects whatever problem which caused it to flee the safety of its cage. Apparently, "Peeppeeppeeppeeppeeppeeppeeppeeppeeppeeppeeppeeppeeppeeppeeppeeppeeppeeppeeppeeppeeppeeppeeppeeppeeppeep!!"
is duckling for "Ohmygodohmygodohmygodohmygodohmygodohmygodohmygodohmygodohmygodohmygodohmygodohmygodohmygodohmygod!!"
The chicks, on the other hand, have a decidedly different approach. One will escape, and likewise plummet to the floor with a kinda wet thud. It will then figure out where in the house the actual people are. You'll see one poke its head around the couch, and having found you walk up. It will then let out a couple of very calm, yet firm peeps. "Peep! Peep peep-peep? Peep."
Which as far as I can tell means, "As the duly appointed representative of the caged chickie alliance, I have been sent to inform you that we are currently lacking in food and/or water. And if it wouldn't be too much of a bother, we would also like a bed-time story."
