Potential Risks of Feeding Crab Shells to Chickens

  1. Choking Hazard: Large pieces of crab shell can be a choking hazard. Always crush or grind them into smaller pieces.
  2. Salt Content: Ensure that the crab shells are free from added salt, as high salt content can be harmful to chickens.
  3. Dietary Imbalance: Feeding too much calcium can lead to dietary imbalances. It’s important to provide a balanced diet alongside the crab shells.
