Poultry Litter Calculator & Bedding & Manure
Beds broilers
Plan your poultry bedding — from birds, floor space and depth get the litter to buy (volume, weight, bags) and the spent litter and manure you'll clear out after the cycle.
Enter your flock & house
Next: keep the litter dry and friable — top up wet or caked patches and ensure good ventilation to protect bird health. When you clear it out, don't waste the 2.97 t of spent litter: it's a valuable nitrogen-rich manure for crops, compost, or biogas feedstock.
Bedding to buy uses rice husk at ~100 kg/m³; tune floor space per bird to your stocking density and welfare standard.

Bed the flock right — and bank the manure
Litter does two jobs: it keeps the flock dry, warm and comfortable, and it absorbs droppings to control ammonia and disease. Lay too little and the floor cakes and birds suffer; lay too much and you waste money. The amount is simple — floor area × depth × the material's density — but it depends on your stocking density, the depth your system needs, and which bedding you use.
This tool sizes the bedding to buy (volume, weight and bags) and also estimates the spent litter and manure you'll clear out — a genuinely valuable, nutrient-rich organic manure and compost or biogas feedstock, not just waste. Keep litter dry and friable for healthy birds, then put the spent litter to work on your fields. Pair it with the Poultry Brooding, Compost & Manure and Biogas tools.

Frequently Asked Questions
How much litter does a poultry house need?+
Multiply the floor area by the litter depth to get the volume, then by the material's bulk density for the weight. A 1,000-bird broiler house at 0.09 m²/bird is 90 m²; at 5 cm of rice husk that's 4.5 m³ ≈ 450 kg. This tool computes the volume, weight and number of bags for your house and material.
How much floor space per bird?+
Broilers need about 0.09–0.10 m² per bird (≈ 10–11 birds/m²); layers on deep litter need more, about 0.15–0.20 m². Give more space in hot climates and for heavier final weights. Enter your space-per-bird and the tool sizes the house and litter accordingly.
How deep should poultry litter be?+
About 5 cm (2 inches) for a single broiler cycle, and 7.5–10 cm for deep-litter layer systems used over months. Deeper litter buffers moisture and composts the droppings, but too deep wastes material. The tool lets you set the depth and scales the quantity.
Which litter material is best?+
Good litter is absorbent, dry and friable: rice husk and wood shavings are the most popular; chopped straw, sawdust and groundnut shells also work. Avoid dusty or mouldy material. The tool covers the common materials with their bulk densities so the weight reflects your choice.
How much manure do birds produce?+
A broiler produces roughly 0.05–0.07 kg of fresh droppings per day; a layer more. Over a 42-day broiler cycle that's about 2.5 kg per bird. The tool multiplies your bird count, daily output and cycle length to estimate total manure, which combines with the bedding into spent litter.
What is spent litter and is it valuable?+
Spent litter is the bedding plus accumulated droppings cleared out after the cycle. It's a valuable organic manure — rich in nitrogen, phosphorus and potassium — and an excellent compost or biogas feedstock. The tool gives the spent-litter tonnage so you can plan its use or sale.
How do I keep litter in good condition?+
Keep it dry and friable — fix leaking drinkers, ensure ventilation, stir caked patches, and top up as needed. Wet, caked litter raises ammonia, causes footpad and breast lesions, and harms growth. Good litter management is one of the cheapest ways to protect bird health and performance.
Can I reuse litter for the next batch?+
In broiler systems litter is sometimes reused for several batches if it stays dry and disease-free, with top-ups and treatment between cycles — it cuts cost but raises biosecurity risk. Many farms clear out fully each cycle. Either way, the cleared spent litter is good manure.
How much bedding cost should I budget?+
Multiply the bags or weight needed by your local material price. Bedding is a small but recurring cost per cycle; cheaper local materials (rice husk near mills, shavings near sawmills) lower it. Use the weight figure from the tool with your price to budget each batch.
Does litter affect ammonia and health?+
Yes — droppings in the litter release ammonia as they break down, especially when wet. High ammonia irritates birds' eyes and lungs and depresses growth. Dry, well-managed litter at the right depth, with good ventilation, keeps ammonia low and birds healthy.
