“Orange Is the New Black,” finishing its seven-season run on July 26, was big. Big in its reach (presumably, though actual viewing figures for Netflix series are still an occult mystery). Big in its influence, as one of the first genuinely original programs in the new medium of streaming. Big in its ambitions to represent faces and situations that had been left off TV screens.

But also, it was simply big — teeming, packed to the ceiling with characters and story — in a way that becomes clear when you peek at Netflix’s spoiler list for its final season.

Oh, the things I cannot tell you about this show! Deaths and releases and imprisonments. Reappearances and disappearances. Love and change and illness and new circumstances and more death. A dozen and a half characters are named; far more are implied.

The list does not say anything about the chickens, though. So I will tell you about the chickens.

If you’ve watched “Orange,” you remember the chicken, in Season 1, rumored to be roaming the grounds of Litchfield, the women’s prison at which the series is set. The bird became a legend, a talisman, a symbol of elusive liberty and hope.
