Moulting in Chickens: How Long Does It Take?

If you have chickens, then you know that they go through periods of moulting. During this time, feathers are shed and replaced with new ones. But how long does chicken moulting last? This post will provide an overview of the moulting process, including when it typically occurs, signs to look for before it begins, what the duration is, tips on making it easier for your chickens, and dietary requirements during the period of moulting.

What Is Chicken Moulting?

Moulting is a natural process in which chickens periodically shed old feathers and grow new ones. It’s an essential part of their growth cycle as it allows them to replace old and damaged feathers with stronger, healthier ones. There are two types of moults: periodic (or partial) moult and annual moult. During a periodic moult, only certain areas of the body may be affected whereas during an annual moult all the feathers are usually lost and replaced within a few weeks or months.

When Do Chickens Typically Moult?

Chickens typically start to moult at around 18-24 months old, although some breeds can begin earlier or later than others. The most common time for moulting is between late summer and early autumn, although depending on the breed, it could occur any time throughout the year.

Signs That A Chicken Is About to Moult

There are several signs that you should look out for when determining if your chicken is about to start moulting. These include: loss of appetite; decrease in egg production; excessive preening; dull plumage; and bald patches where feathers used to be.

What Is The Duration Of Chicken Moulting?

The duration of the moulting process varies from chicken to chicken. Generally speaking, it can take anywhere from 3-4 weeks up to 6-8 weeks depending on the breed, size, health status and environmental conditions. In rare cases, it can take longer for some chickens due to stress or nutritional deficiencies.

Making The Moulting Process Easier For Your Chickens

Making sure that your chickens stay healthy during their moulting period is important so that they don’t suffer unnecessary distress or illness. Here are some ways you can help make the process easier: provide a dust bath area; keep them warm; reduce stressors such as predators; limit access to parasites by keeping feeders clean; and provide extra calcium in their diet.

Shedding Skin And Feathers

During the moulting period, chickens will naturally shed skin cells and feathers. As feathers come off, new ones will start growing in its place. You may also notice tiny pinfeathers poking through the skin – these are immature feathers that will eventually harden and turn into normal feathers once the moulting process is complete.

Feather Replacement During Moulting

When feather replacement happens during moulting, the shedding process can be quite dramatic. At first, only one or two feathers may be lost but over time more and more feathers will fall off until the bird is completely covered in fresh new feathers. This stage of the process can last anywhere from 4-8 weeks depending on the type of bird and other factors.

Tips For Managing Stress During Moulting

Stress can cause chickens to become ill or even die during the moulting process. To reduce stress levels while they are going through moulting, here are some helpful tips: maintain regular feeding times; allow plenty of space for exercise; ensure there is enough shade available; monitor predators closely; and provide lots of comfortable nesting places.

Dietary Requirements When A Chicken Is Moulting

During the moulting process, it’s important that chickens get enough nutrients to keep them healthy and promote strong feather growth. Make sure to provide a high-quality protein source such as mealworms, insect larvae, crickets or fish flakes as well as leafy greens, vitamins and minerals like calcium carbonate or oyster shell grit.


Chicken moulting is a natural process that all chickens go through as part of their life cycle. Knowing what signs to look for, how long it takes and how to manage stress levels during this time can help ensure that your chickens remain healthy and strong throughout the entire process. With proper nutrition and care, they will soon be sporting a brand new set of feathers!
