Ideal Litter Conditions<div>Loose and not caked over. Not too dry or too wet (20-30 % moisture is ideal) Low level of ammonia (less than 20 parts per million) Uniform particle size (No large clumps)</div>

Reusing litter over multiple flocks is a common practice across the U.S. broiler industry, but it comes with potential risks:

• High ammonia levels during early brooding;
• Moisture challenges that must managed to prevent wet litter/poor welfare issues;
• Increased energy (gas and electricity) use to maintain proper air quality; and
• Pathogen carryover that could result in birds breaking with the same disease flock after flock.

Optimal litter depth:

starting out (day-old chicks): 2 to 3cm (about 1 inch)

Growing stage onward: 7 to 10cm (about 3 to 4 inches)

In cold weather, you can go a bit thicker (up to 12 cm) to help with insulation.

In hot weather, keep it lighter to prevent overheating.

Litter management practices for ammonia control:

1. keep it dry: The main cause of ammonia is wet litter. Aim for a litter moisture content of 20 – 25% (feels dry but slightly cool if you squeeze it).

2. Ventilation: Move out moist air, bring in dry air, even if it’s cold outside. Good airflow prevents ammonia buildup even before you smell it.

3. Stir and aerate litter regularly: Turn the litter once or twice a week with a rake or rotavator. This dries it out and breaks up wet, sticky patches that breed bacteria.

4. Manage water lines and drinkers: Fix leaks immediately. Use nipple drinkers if possible (way less spillage than open drinkers).

5. Add new bedding if needed: If an area stays wet (e.g., under drinkers), top up with dry material like wood shavings, rice hulls, or chopped straw.

6. Use litter amendments: Products like acidifiers, zeolite, or gypsum can neutralize ammonia and dry the litter faster. They are especially helpful if ventilation is hard to manage during rainy seasons.

At some point, the deep litter will overtake your area. It will start to smell of ammonia. This smell means that there is excess nitrogen being produced. It also means your nitrogen is gassing off.
