If you are feeding it to layers, than yes you need to add a Ca source. You can uses oyster shells, egg shells or limestone. For a layer feed, your guaranteed analysis should have at least 4x more Ca than P. The other clue is they are calling it a poultry feed and not specifically a layer feed. They do need grit. If they free range than they pick up what they need scratching around in the dirt. If they are locked up , than you need to give them something.
