Why has your hen stopped eating and stop laying eggs?

If your hen has stopped eating and laying eggs, it could be due to several factors such as stress, illness, or changes in environment. Stressors might include a change in habitat, the introduction of new animals, or extreme weather conditions. Illnesses like respiratory infections or parasites can also affect their appetite and egg production. Additionally, age and molting can influence a hen's laying patterns, as older hens may naturally produce fewer eggs.
