I think you're pretty clearly experiencing a false positive on your "major cultural problem" detector. The chickens are cute and comforting, no doubt, and people are referring to them as "emotional support chickens" and "emergency chickens" as a tongue-in-cheek hyperbole. Note how the chickens are given names like "Hennifer Lopez" and "Lindsey LoHEN." You even say that it reads like a joking exaggeration, but apparently your confirmation bias is strong enough to override that observation?
