Something occurred on “Survivor” last week that I’ve seen on several previous seasons, and I’m always confused about.

One of the tribes won a reward of three live chickens — two hens and a rooster. When they got back to camp, several members of the tribe (which hadn’t eaten much besides rice, coconuts, and a crab or two) wanted to eat one of the chickens. So they cut the head off a hen, plucked its feathers, and boiled it.

One of the hens? Why?

Hens produce eggs. Roosters do not. Its only useful purpose would be to fertilize the eggs, but you’re not going to be on “Survivor” long enough to hatch some baby chicks and start a petting zoo. So if you’re going to execute and eat any of the three fowl, why kill one of the protein-producing hens?
