It comes from the same meaning. Children used to be really derided in Spanish it was not uncommon to call a kid “un mojón de mangle” : a mangrove turd and there was a saying “los niños hablan cuando las gallinas mean” : Children should only speak when chickens pee.

Just like Roger Waters did in Mexico when he projected on El Zocalo walls “Trump es un pendejo”
