My mother told me when she was a little girl one of her jobs on the family farm was to manufacture grit. My grandmother would give her a hammer and all the broken ceramic plates and saucers. There was a big metal anvil in the back yard and she would break the damaged dinnerware into small pieces for grit. Yes she still has her eyes and vision at 84 years old. Sounds like OSHA and Social Services would have a field day with this nowadays. She also said that they would order chicks through the mail. Standard charge for pullet chicks was $3.00 per 100.
