ababillarse

Rural Chilean Spanish, used only of domestic fowl coming down with "babilla," a crop/gizzard ailment — essentially a veterinary term for poultry, unrecognizable to most Spanish speakers outside that context.

• La gallina se ababilló después de comer maíz mojado. — The hen came down with babilla after eating wet corn.
• El campesino revisó si el pavo se había ababillado. — The farmer checked whether the turkey had come down with babilla.
• Dicen que ababillarse es común en las aves criadas sueltas. — They say coming down with babilla is common in free-range fowl.

This word is so narrowly veterinary/regional that there's no real mistake to flag beyond assuming it applies to anything but domestic birds — it isn't a general word for "getting sick."
