Tipping Point

The Ungrateful Five once part of much larger flock; now reduced to the parents, two siblings and a maiden aunt.  They had been added to the Foggy Bottoms Resort and Spa endangered species list.  the Face of Everyman wept when he realized their plight.  Was it wrong for the kindly ol’ pensioner to add them to his daily rations and largesse?  Had they lost their edge to remain free to forage?  Had they reached a population tipping point, or was it all in the natural order of things?
