Chooks not laying?
Feather explosion in your backyard?
Half bald patches on your girls?

Moulting is a natural seasonal process in chickens over six months old where they shed old feathers and grow new ones. This normally occurs once a year and in Australia it typically begins in late summer or early autumn as daylight hours start to shorten — often right about the time egg production suddenly drops.

During this time your flock may moult gradually over several weeks, or they may all seem to fall apart at once. Some birds lose only a handful of feathers and look perfectly respectable, while others look like they lost a fight with a determined plucking machine. Either way, one thing becomes obvious very quickly: the egg basket starts looking suspiciously empty.

For many new chicken keepers this sudden drop in egg production can be worrying. In reality, the chicken’s body simply redirects energy away from egg production and into feather replacement. Replacing an entire feather coat is one of the most nutritionally demanding processes a chicken experiences during the year.
 

The Biology of the Egg: It’s All About Light

A very common belief is that chickens stop laying because it gets cold. Temperature has surprisingly little influence on egg production. The real trigger is photoperiod — the length of daylight the bird experiences each day.

A hen’s reproductive system responds to light entering through the eye. When sufficient photoperiod is detected, the hypothalamus signals the pituitary gland located at the base of the brain. The pituitary releases Luteinizing Hormone (LH), which triggers ovulation in the ovary.

Hens generally require around 13 hours of daylight to stimulate the hormonal process responsible for ovulation. When days shorten through autumn and winter, the amount of light entering the eye gradually drops below this level. Ovulation slows and egg production declines or stops.

At the same time the chicken’s body prepares for another demanding task: replacing its feathers. Rather than producing eggs and feathers simultaneously, the bird temporarily pauses egg production and redirects its resources into feather growth. This natural pause often aligns with the moulting season.

From the chicken’s perspective it is simply the ideal time to rebuild its plumage. The bird’s body is essentially saying, “Now seems like a good time to replace my entire feather wardrobe to look brilliant for show season, or simply for strutting their stuff around your backyard.”
 

Health, Husbandry, and the “Mite Factor”

While moulting is the most common reason for a drop in egg production, responsible flock management should always begin with a quick health check. Disease, poor nutrition and stress all affect laying performance.

One specific issue worth checking for is a mite infestation. Mites feed on blood, and heavy infestations can leave chickens anaemic, irritated and stressed. A bird that is physically compromised simply does not have the resources to produce eggs.

Good coop hygiene, regular flock monitoring and proper nutrition support birds through the moulting period and help them return to laying in good condition.
 

My chicken is half bald! What happened?

Some chickens go through what is called an 'explosive' moult and the first time you see this in your chickens can be quite confronting. They will literally go to bed looking relatively normal, then the next morning they may jump off their perch and lose a HUGE chunk of feathers. They might have a shake and lose more. And then walk out of their coop looking almost naked!

It is extreme but it is just up the shocking end of the moulting spectrum. Check out these pics of Rusty the Gold-laced Wyandotte hen who does exactly this every year. If you are on social media, lots of chicken owners share images of their chickens who are experiencing extreme moults and it can be funny, once you get over the shock. 
 

 

The Science of Feather Growth

Feathers may look light and delicate, yet each one is a complex biological structure. Each feather is made primarily from keratin, the same tough structural protein found in hair, nails and animal hooves. Feathers are composed of roughly 90 percent keratin, which explains why producing a fresh plumage requires a substantial amount of protein.

New feathers grow from follicles in the skin. During the early stages of development the feather contains a blood supply, which is why emerging feathers are often referred to as pin feathers or blood feathers.

As the feather matures the blood supply gradually recedes and the feather structure hardens. The outer keratin sheath then begins to break apart and chickens preen to remove these coverings, revealing the feather underneath. Flock mates often assist by gently nibbling around the head and neck where birds cannot easily reach themselves.

New feathers remain sensitive while the blood supply is active, which is why moulting birds often appear quieter or less tolerant of handling.
 

Supporting Your Flock with High Protein and Nutrition

Replacing feathers requires a significant amount of protein, so during the moult chickens redirect dietary protein away from egg production and into feather growth.

Providing a balanced diet during this time is one of the most helpful ways to support your flock. Chickens should always have access to a high quality complete feed containing at least 17 percent protein, such as Laucke Showbird Breeder MP.

Many keepers also provide small daily treats that are naturally high in protein. Meat and bone meal, dried mealworms or black soldier fly larvae contain protein levels above 40–50 percent and can provide a useful nutritional boost when fed in moderation.

If birds appear stressed or slightly off their feed, additional nutritional support may help. Natural Chicken Health Health Plus Poultry Booster can stimulate appetite while providing immune support and a palatable protein lift. Gut health can be supported with Allfarm Probiotic Flakes, while products such as Allfarm Solvita Powder or Anitone Wellness & Vitality liquid provide concentrated vitamins and minerals that may help birds recover condition during this demanding period.
 

Moulting Myths 

 

Feeding fish-based cat food or tuna is a great protein boost

FALSE. Most fish or cat foods contain around 8 percent protein, which is significantly less than high quality chicken feed. Dry cat food is also often high in salt, which can lead to kidney disease in poultry. Fish products are a fine treat, but they are not a reliable protein solution during a moult.

Boosting protein will restart egg laying

FALSE. Extra protein can help feathers grow back faster, but it does not directly restart the laying cycle. Egg production only resumes when the bird has regained sufficient body condition and the photoperiod becomes long enough to trigger ovulation hormones.

Chickens need a jumper to stay warm during moulting

FALSE. Growing new feathers is a sensitive and sometimes uncomfortable process. Replacement feathers begin emerging soon after the old ones are shed and birds can be quite uncomfortable while this growth is underway. Chickens cope far better when this process remains unobstructed, so clothing or jumpers should be avoided. Handling should also be minimised during this period to prevent unnecessary pain or stress while feathers develop.
 

Eggs Are Important to Us. How Do I Get Them Laying ASAP?

Many people keep chickens for the eggs. If eggs are important to you and you want to encourage hens to return to laying sooner, several management strategies can help.

Commercial egg farms maintain consistent production throughout the year by carefully controlling the environment their birds live in. The most important factor they manage is photoperiod.

Hens require around 13 hours of daylight to stimulate the hormonal process responsible for ovulation. When natural daylight drops below this level, laying slows or stops.

Backyard keepers can mimic longer daylight hours by providing artificial light for a few additional hours each day. Installing a low wattage light on a timer inside the coop that activates during the early morning hours can extend perceived day length without disturbing evening roosting behaviour. Solar lights with timers are a popular and inexpensive solution for many standalone coop setups.

Management of the moulting period varies between keepers. Some prefer to allow the process to occur naturally without intervention, while others provide additional protein treats or use lighting to encourage an earlier return to laying. The most important factor remains the health and wellbeing of the flock while their bodies complete the demanding process of replacing feathers.
 

Looking Toward the Solstice

The Winter Solstice marks the shortest day of the year and the turning point many chicken keepers quietly anticipate. Daylight hours begin increasing from this point onward.

As photoperiod gradually rises above the level needed to stimulate ovulation, hormonal signals restart and egg production begins to return. Nature designed this cycle carefully so chicks hatch when environmental conditions are most favourable for survival.

Allowing hens time to moult, rest and rebuild their bodies means they return to laying in far better condition. Feed them well, keep them healthy and before long those freshly feathered hens will be back on patrol filling the egg basket again.
