What is Molting and Why Does it Happen?
Molting is the process of shedding old, worn-out feathers, followed by the regrowth of new, healthy ones. Chickens will experience this natural, healthy process each year, typically in the fall when the days get shorter and temperatures get colder. Molting happens to replace old feathers that no longer do a good job of insulating the chicken and don’t provide protection from things like rain, wind, and snow. New feathers are grown to better protect the chicken from harsh winter weather. When molting starts, chickens will usually begin to lose the feathers around their head and neck, followed by the rest of their body.
While shorter daylight hours and colder weather are typically what triggers molting, there are a few other factors that can cause a molt to happen:
- Stress
- Dehydration
- Malnutrition
- Illness
- Extreme heat
- Broody hens who have recently hatched eggs
