Fowl Cholera: Causes, Symptoms, and Treatment
TL;DR: Fowl cholera, caused by Pasteurella multocida bacteria, can kill without warning — sudden death overnight is often the only sign, alongside greenish-yellow diarrhea and swollen wattles. Treat with alternating Sulpar QR (morning) and Premoxil (afternoon) over 6 days, resting on Day 4, then Vitmin Pro for recovery. Bury or burn dead birds immediately; never just discard them.
What Is Fowl Cholera?
Fowl cholera is caused by the Pasteurella multocida bacteria, and it’s one of the most dangerous poultry diseases because it can kill birds without any warning — sometimes you simply wake up to find a bird dead. See our guide to common gamefowl diseases for how it compares to other flock threats. Unlike internal parasites, which drain a bird’s condition slowly over weeks, cholera can take one down overnight — act immediately at the first suspicious symptom.
What Are the Symptoms of Fowl Cholera?
Sudden death is often the first sign of fowl cholera — sometimes a bird simply dies overnight with no warning beforehand.
- Sudden death — sometimes this is the first sign, the bird dies overnight
- Greenish-yellow diarrhea
- Swollen wattles and joints
- Difficulty breathing (labored breathing)
- Darkening comb and wattles (turning purple)
- Loss of appetite, listlessness (depression)
How to tell cholera from typhoid/pullorum: Both diseases can cause sudden death, which is why the two get mixed up in practice. The droppings color is the tell — cholera produces greenish-yellow diarrhea, while fowl typhoid and pullorum instead produce white or chalky droppings. If a bird dies suddenly without a clear cause, check the rest of the flock for symptoms and note the droppings color before deciding which protocol to run.
How Do You Treat Fowl Cholera With Sulpar QR and Premoxil?
Treat fowl cholera with a 6-day alternating protocol — Sulpar QR every morning and Premoxil every afternoon — followed by a 3-day recovery phase. These amounts are given per gallon of water, not scaled to a specific bird weight — this guide doesn’t state a weight basis, so follow the product label if you’re dosing a bird noticeably lighter or heavier than a gamefowl.
| Day | Morning | Afternoon |
|---|---|---|
| Day 1 | Sulpar QR — 5g per gallon of water | Premoxil — 10g per gallon of water |
| Day 2 | Sulpar QR — 5g per gallon of water | Premoxil — 10g per gallon of water |
| Day 3 | Sulpar QR — 5g per gallon of water | Premoxil — 10g per gallon of water |
| Day 4 | Plain water only (REST DAY) | Plain water only (REST DAY) |
| Day 5 | Sulpar QR — 5g per gallon of water | Premoxil — 10g per gallon of water |
| Day 6 | Sulpar QR — 5g per gallon of water | Premoxil — 10g per gallon of water |
Sulpar QR is specifically indicated for the treatment of fowl cholera caused by Pasteurella multocida.
Recovery Phase
| Day | Medication |
|---|---|
| Day 7–9 | Vitmin Pro — 10g per gallon of water, daily |
How Do You Prevent Fowl Cholera?
Biosecurity is the single biggest prevention factor for fowl cholera — limiting who and what enters your farm cuts off its main routes of spread.
- Biosecurity — limit the people and animals entering your farm area
- Isolate newly arrived birds before introducing them to the flock
- Dispose of dead birds properly — bury or burn them, do not simply discard them
- Disinfect everything after an outbreak
What Are the Golden Rules for Treating Fowl Cholera?
- Never mix Sulpar QR and Premoxil in the same water. Sulpar QR in the morning, Premoxil in the afternoon — keep them separate.
- Do not mix medication with Vitmin Pro on the same day during treatment. Give Vitmin Pro only during the recovery phase (after the treatment protocol).
- Always use freshly prepared medicated water each day. Do not reuse yesterday’s mix.
- Remove all other water sources during treatment to ensure the birds drink the medicated water.
- Isolate sick birds immediately from the healthy flock — do not wait.
- Complete the entire treatment course even if the bird looks fine by Day 2. Stopping early risks creating drug-resistant bacteria.
- Prevention is better than treatment. Keep the coop clean, sand dry, deworm regularly, and vaccinate properly.

Frequently Asked Questions
What is the first sign of fowl cholera?
Sudden death is often the first sign — a bird can die overnight with no warning symptoms beforehand. If you find a bird dead with no clear cause, check the rest of the flock immediately.
What causes fowl cholera?
Fowl cholera is caused by the Pasteurella multocida bacteria. It is one of the most dangerous poultry diseases because it can kill without warning.
How long is the Sulpar QR and Premoxil treatment protocol for fowl cholera?
Six days total: Sulpar QR each morning and Premoxil each afternoon, with Day 4 as a plain-water rest day, followed by a 3-day recovery phase (Day 7-9) using Vitmin Pro.
Can Sulpar QR and Premoxil be mixed in the same water?
No. Give Sulpar QR in the morning and Premoxil in the afternoon, kept completely separate. Vitmin Pro is for the recovery phase only, not during treatment.
What should you do with a bird that dies of fowl cholera?
Bury or burn it immediately — do not simply discard the carcass. Disinfect the area afterward to limit further spread.
How do you prevent fowl cholera?
Practice biosecurity by limiting the people and animals entering your farm, isolate newly arrived birds before mixing them with the flock, and disinfect everything after an outbreak.
Is fowl cholera the same as fowl typhoid or pullorum?
No. Cholera droppings run greenish-yellow, while typhoid and pullorum produce white or chalky droppings instead. Both can cause sudden death, so check droppings color and bird age to tell them apart.
What happens if treatment stops early?
Stopping early even if the bird looks fine by Day 2 risks creating drug-resistant bacteria. Complete the full 6-day course every time.
