Poultry Litter Calculator & Bedding & Manure

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
