If you see white material in chicken droppings, do not rush straight to the medicine shop. The white part may be completely normal. Chickens normally pass faeces, urine and a white or cream material called urates together.
The time to worry is when the droppings have clearly changed from normal and the change keeps happening, especially when several birds are affected or you also see weakness, pasted vents, poor appetite, poor growth or deaths.
“White diarrhoea” is a description, not a diagnosis. Pullorum disease is one important cause, particularly in young chicks, but it is not the only reason a farmer may see white or watery droppings.

First Check: Is the White Part Actually Normal?
A normal chicken dropping usually has three parts:
- Faeces — usually brown, greenish-brown or grey-brown.
- Urates — the normal white or cream paste.
- Urine — usually a smaller amount of clear liquid.
So a white cap on an otherwise normal dropping is not automatically disease. One unusually wet dropping is also not enough to diagnose anything.
Hot weather can make birds drink more, which can increase the liquid around the dropping. Feed changes and other management factors can also alter what you see. Normal caecal droppings are softer, darker and usually smell stronger than ordinary droppings.
White Droppings: A Quick Farm Check
Is it simply a normal white urate cap, or is the whole dropping repeatedly watery or abnormal?
Check appetite, drinking, activity, pasted vents, growth, breathing and mortality.
One bird and one dropping are different from many chicks becoming weak at the same time.
White droppings alone cannot tell you which medicine, if any, the flock needs.
When White Diarrhoea Can Mean Pullorum Disease
Pullorum disease is caused by Salmonella enterica serovar Gallinarum biovar Pullorum. It was historically called bacillary white diarrhoea because sick young chicks can develop whitish faecal material pasted around the vent.
Young chickens are the main concern. Affected chicks may huddle close to heat, stop eating, become weak and dull, develop pasted vents and die in increasing numbers. Turkey poults can also be affected. Birds that survive infection can become carriers, and infected hens can pass the organism through eggs.
That last point is important. Pullorum disease is not simply a diarrhoea problem that disappears when the dropping looks better. It can become a breeding-flock and chick-source problem.
Pullorum Disease Is Relevant to Nigerian Poultry
This is not only a foreign textbook disease. Nigerian studies have documented Salmonella problems in commercial poultry, including the poultry-adapted organisms associated with Pullorum disease and fowl typhoid. Research from North-Central Nigeria has also identified salmonellosis as a continuing poultry-farm challenge, with biosecurity and flock-management practices among the important risk factors.
That makes chick source very important. Buy day-old chicks and hatching eggs from reputable sources with proper breeder-health and hatchery control. If several newly arrived chicks begin showing pasted vents, weakness and unusual mortality, investigate the source as well as conditions on your own farm.
Other Reasons Chickens Can Pass White or Watery Droppings
Extra urine and increased drinking
Sometimes what looks like diarrhoea is actually a formed dropping surrounded by extra liquid. Heat stress and increased water intake can contribute to this. Check whether the faecal part is still formed before deciding the bird has intestinal diarrhoea.
Coccidiosis
Coccidiosis can cause diarrhoea, weakness, poor appetite, poor growth and mortality. Some species cause obvious blood; others do not. White colour alone cannot diagnose coccidiosis. See our complete guide to coccidiosis in chickens and our explanation of the Eimeria lifecycle.
Worms and other intestinal disease
Worm burdens, bacterial enteritis and other intestinal problems can produce poor growth, diarrhoea and weakness. Many poultry diseases share the same outward signs. Our guide to worms in poultry explains why treatment should match the parasite involved.
Feed, water and management problems
Spoiled feed, contaminated water, sudden feed changes, toxins and severe management stress can change droppings. Check what changed recently, but do not blame feed or heat automatically when birds are becoming seriously ill.
Kidney or wider systemic disease
Because the white urate portion is part of the bird’s waste-excretion system, unusually large amounts of white material or excessive clear liquid can also occur with wider health problems. A dropping cannot tell you by itself which organ or disease is responsible.

What to Do Immediately When Several Birds Have Abnormal Droppings
- Check the birds, not only the floor. Look at appetite, drinking, activity, body condition, vents, breathing and mortality.
- Check the age and source. White pasted vents and mortality in very young chicks deserve more urgent investigation for Pullorum disease and other chick diseases.
- Give clean water and proper feed. Sick birds can dehydrate quickly. Make sure drinkers are accessible and clean.
- Keep the environment dry and clean. Remove wet or badly soiled litter and stop faecal contamination of feeders and drinkers.
- Separate obviously sick birds where practical. Do this without creating excessive stress, and restrict unnecessary movement between pens.
- Record what is happening. Note the number sick and dead, age, pen, feed changes and when the problem started. Photograph fresh droppings if useful.
- Get diagnostic help when the problem is serious or spreading. Fresh samples, post-mortem examination, bacterial culture, PCR, faecal examination or other tests may be appropriate depending on what is suspected.
When You Should Act Urgently
Do not spend several days experimenting with different medicines if you are seeing rapidly rising mortality, many weak or huddling chicks, widespread pasted vents, severe dehydration, birds refusing feed or water, blood or black material in droppings, serious breathing or nervous signs, or disease spreading quickly through the flock.
Those are situations where identifying the disease becomes more important than finding a quick “white diarrhoea treatment.”
There Is No Single White-Diarrhoea Medicine
This is where farmers can lose time and money. An antibiotic, anticoccidial and dewormer do completely different jobs. Antibiotics do not kill Eimeria. Anticoccidials do not treat Pullorum disease. Dewormers do not treat either one.
Do not choose penicillin, tetracycline, amprolium or another medicine simply because somebody says it stops white stool. Wrong treatment can hide signs, delay diagnosis, waste money, contribute to antimicrobial resistance and create meat or egg residue problems.
For veterinary medicines, use products approved for the bird and production class, follow the current label or veterinary direction, and observe meat and egg withdrawal requirements.
A Special Warning About Treating Pullorum Disease
For confirmed Pullorum disease, the long-term objective is not simply to make individual chicks look better. Authoritative veterinary guidance focuses on eliminating the organism from breeding populations because recovered birds can remain carriers and transmit infection.
This is why suspected Pullorum disease should involve veterinary or laboratory diagnosis and flock-level control. Repeated antibiotic treatment without dealing with infected breeding stock, chick source and biosecurity can leave the real problem in place.
How to Reduce the Risk
- Buy chicks and hatching eggs from reputable, health-controlled sources.
- Keep good brooder and hatchery hygiene.
- Keep litter dry and feeders and drinkers clean.
- Do not casually mix birds of different ages or unknown health status.
- Quarantine new birds where appropriate.
- Control rodents, wild birds and unnecessary movement between houses.
- Investigate unusual chick mortality instead of repeatedly changing medicines.
- Use a flock health and vaccination programme appropriate to your farm and local veterinary guidance.

Frequently Asked Questions
Is the white part of chicken poop normal?
Usually, yes. White or cream urates are a normal part of chicken droppings. Concern rises when there is a persistent major change or when abnormal droppings occur with sick birds.
Does white diarrhoea mean Pullorum disease?
No. Pullorum disease is an important possibility, especially in young chicks with pasted vents, weakness and mortality, but white droppings alone cannot confirm it.
Should I give antibiotics immediately?
Not because of dropping colour alone. Antibiotics only work against susceptible bacteria and will not treat coccidiosis, worms, viral disease or management problems.
What is the most important clue?
The pattern across the flock. Age, chick source, mortality, appetite, water intake, pasted vents and other signs tell you far more than colour alone.
