This cute little blurb came from the inimitable Atlas Obscura:
Despite the headline – Egg Vending Machine at Glaum’s Ranch: At this California chicken ranch four bucks will get you 22 eggs and a chorus of dancing animatronic poultry – inflation has taken its toll. $4 will only get you 18 eggs nowadays. But you still get the dancing chickens!
Just south of Santa Cruz, in Aptos: http://www.atlasobscura.com/places/the-egg-vending-machine-at-glaums-ranch
