Ulcerative Enteritis (Quail Disease) in Quail
The disease so deadly to quail it's literally named 'quail disease' — watch for white, watery droppings, hunched birds, and rapid deaths. It's bacterial, it spreads in droppings, and it needs antibiotics fast.
Ulcerative enteritis is the one disease every quail keeper should know by name, because Coturnix and bobwhites are its favorite victims — it kills quail at rates that barely touch chickens. A Clostridium bacterium ulcerates the intestine; birds go from apparently fine to hunched, white-diarrhea, and dead in as little as one to three days, and in unlucky coveys losses can pass half the flock. Speed and hygiene are everything.
What causes it
The bacteria arrive via droppings — wild birds, contaminated ground, new birds, dirty equipment — and persist in soil and litter for months to years. Outbreaks love stress: crowding, damp litter, a recent coccidiosis episode (the two often chain together), or mixing new birds without quarantine.
What to do right now
At first suspicion — white watery droppings plus a listless, humped-up bird, especially with a death — separate the sick, then treat the entire covey through the water: bacitracin is the classic effective choice, with penicillin-class drugs as the vet-guided alternative. Move fast on hygiene the same day: remove droppings buildup, swap to fresh dry litter, sanitize waterers and feeders, and get birds off contaminated ground if they're pen-raised on soil. Support sick birds warm with electrolytes. A dead bird plus a state-lab necropsy turns 'probably' into 'certainly' for a few dollars and tells you exactly what you're fighting.
When it's a vet problem
This page IS the vet page: any cluster of deaths with white diarrhea deserves a professional diagnosis and the right prescription. Bring a fresh dead bird (refrigerated, not frozen) to your vet or state poultry lab.
Preventing it next time
Quarantine every incoming bird two to four weeks, keep litter dry and droppings managed, don't run quail on ground recently used by chickens or wild-bird-heavy areas, control coccidiosis in the young (it opens the door), and clean equipment between coveys.

Catch problems like this a day earlier
The keepers who spot ulcerative enteritis (quail disease) early are the ones tracking their covey. Quail Keeper Max logs your birds' health notes, weights, egg production, and losses — so a bad trend shows up on a chart before it shows up in the pen. And when something does look off, ask Captain Coturnix, your personal quail advisor: he reads your flock's records and helps you figure out what changed.

A note from one keeper to another: this guide reflects established quail-keeping practice and first-response care, but it isn't veterinary medicine, and no article can examine your bird. When a symptom is severe, worsening, or just doesn't add up, a qualified avian or poultry veterinarian is the right call — and for emergencies, call one first. Your state's poultry diagnostic lab is also a keeper's best friend when losses need real answers.
