Litter management through a cycle
Litter is not bedding. It is the surface the bird lives on, the reservoir for every gut parasite you have, and the main source of the ammonia in your shed.
Awaiting veterinary review. This guide is written from published industry practice and has not yet been checked by our domain advisor. Confirm anything clinical with your own veterinarian before acting on it.
Most farms think about litter twice: when they put it in and when they take it out. In between it is quietly setting your FCRFeed conversion ratio — kilograms of feed to put on a kilogram of live weight. The single most useful number in broiler production, because feed is 60–75% of what the bird cost.Glossary →, your leg condition, your downgrade rate and your ammonia level.
What you are actually managing
Moisture. Everything else follows from it. Dry, friable litter that you can crumble in your hand is doing its job. Litter that cakes into a hard mat, or that holds a footprint, has failed.
The number usually quoted as the target is 20–25% moisture. You will not be measuring that. The hand test is what farms actually use, and it works: pick up a handful and squeeze. It should form a loose ball that breaks apart when you open your hand. If it stays in a ball, it is too wet. If it will not form one at all, it is dust-dry and you have a different problem.
Where the water comes from
Litter does not get wet on its own. Every damp patch has a cause:
| Cause | What it looks like | | --- | --- | | Leaking or badly set drinkers | Wet strip directly under the line | | Too little ventilation | Whole-shed damp, worse in cold weather | | Gut upset — coccidiosis, enteritis, a feed change | Wet droppings across the shed | | High stocking density | Nowhere for moisture to go | | Roof leaks, side-curtain rain ingress | Wet at the edges, after rain | | Salt or excess protein in the ration | Birds drink more, litter follows |
Almost every persistent wet-litter problem in Pakistan is drinker height, ventilation, or coccidiosis. Check those three before anything else.
Why ammonia matters more than it looks
Wet litter plus uric acid produces ammonia. You smell it at roughly 20 ppm. By the time it stings your eyes at the bird’s level, it has already:
- Damaged the lining of the airways, which is exactly the defence that keeps IB and mycoplasma out
- Suppressed feed intake
- Started to cause eye irritation and, at sustained high levels, blindness
Test at bird height, not standing up. Ammonia is heaviest where the birds are. A shed that smells acceptable to you at head height can be unpleasant at 10 cm.
Depth and material
Rice husk is the most common material in Pakistan, and wheat straw and wood shavings are both used. Rice husk works well: it is absorbent, cheap and locally available.
Typical depth is around 5–8 cm, deeper in winter and shallower in hot weather. Too thin and moisture reaches the floor; too thick and it costs money without returning anything.
Whatever you use, it must be dry and clean going in. Mouldy husk is a direct route to mycotoxins and to Aspergillus.
Through the cycle
Week 1. Preheat the floor before the chicks arrive — cold litter pulls heat straight out of a chick’s body regardless of the air temperature. Chick paper over the litter for the first few days.
Weeks 2–4. Stir caked areas, particularly under drinker lines. Top up wet patches with fresh material rather than trying to dry them in place.
Weeks 4 onward. The birds are producing far more moisture and heat. Ventilation is doing most of the work now. Keep walking the shed and breaking up cake before it spreads.

Reusing litter
Common on Pakistani farms and defensible on a single-age site with a clean history. It is a bad idea if the previous flock had coccidiosis, necrotic enteritis or any significant disease event — you are handing the next flock the same pathogen load on day one.
If you reuse, the minimum is: remove all cake, windrow or heap the remainder to heat, and leave a proper downtime.

What the spent litter is worth
It is a genuine by-product, not waste. Poultry litter is a valued fertiliser and sells to crop farmers. Budget it as income rather than as a disposal cost — and never feed it back to ruminants.
