There are stories of the chickens with gold flakes in the gizzards at one stage stop by here. (Dyke mining District) but I digress
The Contents of an Ostrich’s Stomach
Frederick William Bond took the photo below at the London Zoo showing the items found in an ostrich's stomach following an autopsy: a lace handkerchief, a buttoned glove, a length of rope, a plain handkerchief, copper coins, metal tacks, staples, hooks, and a four-inch nail. The nail had killed it.
The photo is undated, but I'm guessing it was taken sometime in the 1930s.
Along similar lines is this story from 1972 about items found in the stomach of an ostrich at a private French zoo: coins, telephone tokens, and stones. What wasn't found was the diamond watch it had snatched off a spectator the previous year.
