Your broody hen may be fine on her own, but it's important to monitor her well-being. Broody hens tend to become protective and stay on their nest, even if there are no eggs to hatch. Ensure she has access to fresh water, food, and a safe, comfortable environment. Observe her behavior for signs of distress or illness. If she seems healthy and continues to eat and drink, she should be okay. However, if you notice any concerning symptoms or a decline in her condition, consult a veterinarian who specializes in poultry for proper guidance and care.
