So I’ve lost a chicken, turkey and a duckling. Chicken was 4-5 months, duckling 6 weeks and turkey was 10 weeks. All 3 seemed to keep to themselves before they died, all have died within past two months. The duckling was put into quarantine and it throw up and had really smelly poo, it also had a seizure as it died. I noticed something was off today and it died about 10 hours later. Any idea what’s going on here?
