Why are my Laying Hens Loosing Feathers?

You walk out in the morning to find feathers everywhere.... OH NO! you think, has there been a predator attack?

Feathers are everywhere! .... On the coop floor, scattered through the run, maybe even a few sad-looking patches on your normally fluffy hens. You do a head count! all accounted for!

"Why are my chickens losing feathers?", Not sure why? you're certainly not alone! It's a common sight in backyard flocks, and while sometimes it's perfectly normal, other times it signals something that needs your attention.

As busy mums and dads juggling a million things, we want to do the best for our chooks without getting bogged down in complex science. So, let me break down the main reasons for feather loss and look at practical solutions to get your girls looking gorgeous again.

Here are the top culprits behind those missing feathers:

1. The Big Annual Shed: Understanding Moulting

This is often the prime suspect, especially as autumn rolls around.

Moulting is a completely natural, yearly process (for most) where chickens shed their old, worn-out feathers and grow a shiny new set, usually getting them ready for winter. Think of it like their version of getting a new coat! Some breeds might do this more dramatically than others.

Growing new feathers takes a lot of energy and protein (feathers are about 85% protein!). During this time, your hens might look a bit ragged, stop laying eggs, and can be more sensitive or grumpy.
What to do: Give them extra support! Boost their protein intake – switching to a high-protein feed during the moult is ideal. This is where the cheaper, low-protein feeds really start to take their toll. Ensure they always have fresh water and minimise stress during this sensitive period.

2. Pesky Parasites: When Mites and Lice Move In

These little insects can cause big irritation, and can lead to fatalities if left. Lice and mites cause anemia, so the first sign of these pesky parasites means a egg laying drop in numbers or a complete stop in laying.

External parasites like mites and lice feed on your chickens' skin or feathers, causing intense itchiness. You might notice your hens scratching, preening excessively, or developing bald patches, often around the vent, under the wings, or on their back/neck. You might even see the tiny critters themselves or their eggs if you look closely at the skin and base of the feather shafts.
Constant irritation leads to feather damage and loss from scratching and over-preening. A heavy infestation can also cause anaemia, weight loss, and make your hens more vulnerable to other illnesses.
Regularly check your hens for parasites. Keep the coop super clean, paying attention to roosts and nesting boxes where mites love to hide (especially red mites, which feed at night!). Treat infestations promptly. Regular preventatives such as Stalostan and Avian Insect Liquidator can be effective options to have on hand.

3. Flock Politics & Stress: Hen Pecking Explained

Sometimes, the feather loss is caused by other birds in the flock.

Chickens have a social hierarchy known as the "pecking order." A bit of minor pecking is normal as they establish who's boss when new birds are introduced to a existing flock, however, excessive, aggressive pecking that draws blood or causes significant feather loss can also be a sign of stress.

Persistent bullying can cause injury, stress, and prevent victimised hens from accessing food and water. Stress-induced pecking often points to an underlying issue in their environment. Is your flock over crowded? Can all birds access food and water without being watched by other flock members?
Observe your flock. Is it just minor squabbles, or is one hen being relentlessly targeted? Ensure there's enough space for everyone – overcrowding is a major stressor. Provide enrichment like hanging cabbages, straw bales to sit on, and ideally, a deep litter system for scratching in to combat boredom. A Great idea is to use a healthy distraction like a peck block
Make sure there are enough feeders and drinkers. If bullying is severe and causing injury, you may need to separate the bully or the victim temporarily.

4. Fuelling the Feathers: Modern Nutrition Needs

What your hens eat directly impacts their plumage. Lets think about that for a moment.

Forget the old days of feeding chooks just kitchen scraps! Today's highly domesticated hens have been bred for fantastic egg production, and their bodies need high-quality, balanced nutrition to thrive – and that includes growing and maintaining healthy feathers. Things like bread, pasta, oats or too many leftovers just don't cut it and can even lead to health problems.
Poor nutrition, especially lacking sufficient protein or essential vitamins and minerals, directly impacts feather quality, making them brittle, weak, or slow to regrow after a moult. Consider giving meal worms as a healthy treat! Remembering that treats should be exactly that ... a treat offered in moderation!
Provide a high-quality, balanced layer feed specifically formulated for laying hens as the main part of their diet. Look for feeds like Laucke Showbird Breeder or Red Hen 17 that offer complete nutrition. Treats are fine in moderation, but shouldn't replace their proper feed.

5. The Coop Environment: Comfort is Crucial

Your chooks' home base plays a role too.

While much of the information found online is focused on heat stress (definitely an issue in Aussie summers!), the overall environment matters. A poorly ventilated coop can lead to humidity build-up and ammonia from droppings, which can irritate skin and potentially damage feathers. A dirty coop is also a haven for parasites and bacteria. Pine Shavings and Hemp Beddings are the best choices in bedding. They stay clean for longer periods, helping with mite and lice control and can be used on your garden as compost after use in the chicken coop. We do not recommend straw and hay as they are often a big instigator for mites and lice breeding and also become heavy with bacteria quickly.
Lack of shade forces hens into stressful, hot conditions. Do you birds have adequate space to free range and explore (enrichment each day)? or are they bored in their environment?
Birds should have approximately 2 square meters per bird in space as a minimum

there are lots of great ideas that can be simple to make, but adds super enrichment to your coop! get creative and have a go!

A comfortable, clean, and safe environment reduces stress, minimises parasite risks, and helps hens regulate their body temperature – all contributing to better feather health.
Ensure the coop has good ventilation (but is draught-free in winter). Keep bedding clean and dry. Provide ample shade in the run using shade cloths, trees, or access under a verandah. In summer heatwaves, offer cooling treats like frozen watermelon or cucumber pieces, and always ensure plentiful cool, fresh water.

Your Feather Fix-It Toolkit: Helping Hens Heal

Feeling empowered to tackle the feather loss? Here are some quick tips summarised:

Boost Protein Power: Especially during moult, ensure a high-protein diet. A quality feed like Laucke Showbird Breeder is a great base. Meal worms are a great treat full of protein.
Wonderful Water: Keep fresh, clean water available 24/7. Consider adding electrolytes or freezing chopped fruit/veg in water blocks on hot days.
Cleanliness Counts: Maintain a hygienic coop and run to deter parasites and reduce stress.
Banish the Bugs: Regularly check for mites/lice and treat promptly if found using effective products like or protect the coop environment with Stalosan or Avian Insect Liquidator
Stress Support: Consider a supplement like Avi Vital or Anitone during stressful times (moult, heatwaves, integration of new birds) to support their immune system.
Soothe Sore Skin: If skin looks irritated from pecking or parasites, a warm bath can help soothe and promote healing. If you are seeing wounds or blood from pecking, spray with Cetrigen to promote healing and stop feather picking
Watch the Flock Dynamics: Monitor pecking behaviour. Intervene and separate birds if injuries occur. Ensure boredom-busting activities are available!

Seeing feathers fly can be worrying, but by understanding the common causes – from natural moulting to parasites or stress – you can take simple, effective steps to help your backyard chooks stay healthy, happy, and beautifully feathered.
