Flock Validation

4. Tag Uniqueness

• No two living sheep should have the same tag number
• Deceased sheep may share tags with living sheep (tags get reused)
• Tags noted as "retagged" should be verified

5. Pen Assignments

• Every sheep with status = "alive" should have a pen assignment
• No deceased sheep should be listed in active pens
• Pen ram assignments should match the pens object

6. Health Records

• Sheep on the "weak resistance" list should have health.weak_resistance = true
• Treatment dates should be chronological
• FAMACHA scores should be 1–5
