Scratching, feather loss and restless hens can all point towards external parasites, but “mites” and “lice” are not the same problem. Correct identification matters because where the parasite lives, when it is active and how it spreads can differ.
For backyard keepers, three common concerns are red mite, Northern Fowl Mite and lice. Regular flock checks make it easier to spot a problem before it becomes severe.
Red mite: mostly a coop problem
Red mites are tiny parasites that usually hide in the chicken house during the day and feed on hens at night. The British Hen Welfare Trust (BHWT) advises checking cracks, perch ends and crevices because the mites may be easier to find in the housing than on the bird.
Possible signs include restless hens, reluctance to enter the coop, increased scratching, feather pecking and pale combs or wattles in more serious infestations.
Our Chicken Mite & Pest Control collection includes products intended for poultry pest-management routines. Always use each product exactly as directed.
Northern Fowl Mite: lives on the bird
Unlike red mite, Northern Fowl Mite spends its life cycle on the host. BHWT guidance notes that mites often congregate around the vent area and can cause irritation, frequent preening and darkened or dirty-looking feathers around the vent.
Because populations can increase quickly, birds showing heavy infestation, weakness or pale combs should be assessed promptly.
Chicken lice: look for adults and nits
Lice also live on the bird. Adult lice are larger than red mites and can often be seen moving when the feathers are parted. BHWT describes clusters of eggs, or nits, attached firmly to the base of feather shafts as a useful sign.
Common signs include feather loss, scratching and redness. Lice do not usually spend the day hiding in coop cracks in the same way as red mite.
Where should you check?
For red mite, inspect the housing: underside of perches, joints, nest boxes, removable trays and cracks. For lice and Northern Fowl Mite, carefully inspect the bird, especially around the vent, under the wings and at the base of feathers.
Handle hens calmly and avoid causing unnecessary stress. If you are unsure what you are seeing, a poultry-experienced vet can help identify the parasite.
Cleaning still matters
Good coop hygiene supports parasite management. Remove soiled bedding, clean equipment and follow the directions on any disinfectant or pest-control product.
See Chicken Coop Care for housing-cleaning products and Chicken Health & First Aid for everyday flock-care products.
Be careful with treatments
Do not assume every powder, spray or insect-control product can be used directly on birds. Some are for housing only. Others have specific directions for bird application.
Read the full label, follow restrictions around eggs, feed and water, and use appropriate protective measures. If a product's intended use is unclear, do not improvise.
Quarantine and equipment
New birds and second-hand housing or equipment can introduce parasites. Inspect and clean used items before adding them to the flock area, and follow sensible quarantine procedures for new hens.
When to contact a vet
Seek veterinary advice if a bird is weak, pale, losing condition, has significant skin damage, stops eating or drinking, or if a parasite problem is not improving. Severe blood-feeding mite infestations can cause anaemia.
Frequently Asked Questions
Are red mites the same as chicken lice?
No. Red mites are mites that commonly hide in the coop during the day and feed at night. Lice live on the bird and their eggs can often be seen attached to feather shafts.
Can chicken lice live on people?
Chicken lice are adapted to their avian hosts and do not establish a normal life cycle on people. Good hygiene is still sensible when handling infested birds or bedding.
Where do I look for red mite?
Check perch ends, cracks, joints and dark crevices in the chicken house, especially after birds have roosted overnight.
Why are my hens scratching?
Parasites are one possible cause, but skin irritation, feather growth, moulting and other health problems can also cause scratching. Check the whole bird and environment.
