Chicken Droppings Color Chart & Poultry Diarrhea Diagnostic Guide

Accurately diagnosing diarrhea in chickens begins with recognizing healthy normal variation. Chickens evacuate two completely distinct forms of excreta each day:

• Enteric (Intestinal) Droppings: Produced 12 to 16 times per day. These consist of a firm, coiled, grayish-brown or greenish cylinder capped with white chalky paste. The brown portion represents digested feed solids, while the white cap consists of concentrated uric acid crystals precipitated by the kidneys to conserve water.
• Cecal Droppings: Produced once every 8 to 10 evacuations (roughly 1 to 3 times daily). The paired ceca ferment fine fiber and non-starch polysaccharides through anaerobic bacterial digestion. When emptied, cecal droppings appear as a glossy, mustard-brown or caramel-colored pudding with a pungent odor and no white urate cap. Flock owners often mistake normal cecal evacuations for pathological diarrhea.

Pathological diarrhea in poultry differs fundamentally from cecal droppings: it recurs continuously, lacks structure, soils vent feathers with sticky paste ("pasting up"), and contains abnormal inclusions like fresh blood, necrotic mucosal casts, or excessive fluid halos spreading across bedding.

Investigating diarrhea in hens requires separating infectious pathogens from environmental and nutritional imbalances:

In commercial laying flocks, diarrhea in hens frequently coincides with peak egg production (24 to 32 weeks of age). Laying hens consume large quantities of calcium carbonate; excess fine limestone dust can cause osmotic hyperosmolar flushing in the small intestine, producing transient wet droppings without pathogen involvement.

Regardless of the underlying primary cause, acute diarrhea in poultry quickly induces severe metabolic dehydration, hypokalemia, and acid-base decompensation. A bird weighing 1.8 kg (4.0 lbs) loses up to 10% to 15% of its total body water within 24 hours of profuse diarrhea.

Emergency Veterinary Rehydration Formula (Per 1 Liter / 0.26 Gallons of Drinking Water):

Administer electrolyte solutions for 3 to 5 consecutive days alongside specific targeted antimicrobials (such as Amprolium for coccidia or appropriate antibiotics for confirmed bacterial enteritis). Avoid running electrolytes longer than 5 days, as prolonged sodium supplementation can cause osmotic renal flushing.

An immediate consequence of flock-wide diarrhea in poultry is damp, caked litter. Healthy poultry litter maintains a moisture content between 20% and 25%. When droppings turn watery, litter moisture quickly exceeds 35% to 40%:

• Footpad Dermatitis (Bumblefoot & Hock Burns): High moisture combined with uric acid creates an alkaline, caustic slurry that erodes the keratinized plantar skin of the feet, creating deep ulcerated footpad lesions.
• Ammonia Volatilization: Microbial breakdown of wet uric acid accelerates at barn temperatures above 22°C (71.6°F), driving ambient ammonia past 25 ppm. Ammonia gas destroys tracheal ciliated epithelial cells, paving the way for secondary E. coli and Mycoplasma respiratory infections.
• Intervention: Remove wet caked bedding immediately, top-dress with 5 to 7 cm (2.0 to 2.8 inches) of dry wood shavings, and boost minimum ventilation rates by 20% to 30% to exhaust excess humidity.
