How to Use This Calculator
  1. Enter the flock size and house area in square feet to calculate litter volume needed.
  2. Set the grow-out period in days and select the drinker type: 0 = open trough, 1 = nipple drinker.
  3. Review Recommended Litter Depth and Litter Volume to plan your bedding material order.
  4. Check End Moisture Estimate and Moisture Assessment — litter above 30% moisture requires caking management.
  5. Monitor Ammonia Risk Level throughout the flock cycle and increase ventilation if it rises to high.

What each input means

Flock Size
Number of birds placed in the house.
House Area
Total floor area of the poultry house in square feet.
Grow-Out Period
Length of the grow-out period in days. Typical broiler cycle is 35-49 days.
Drinker Type
Water delivery system: 1 = Nipple drinkers (less spillage), 2 = Bell/trough drinkers (more spillage).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Flock Size = 25000, House Area = 20000, Grow-Out Period = 42, Drinker Type = 1 = 4 input(s) provided
  2. Calculate Recommended Litter Depth
    Recommended Litter Depth
    4 = 4
  3. Calculate Litter Volume Needed
    Litter Volume Needed
    246.9 = 246.9
  4. Calculate End Moisture Estimate
    End Moisture Estimate
    80 = 80%
  5. Calculate Moisture Assessment
    Critical — wet litter, take corrective action = Critical — wet litter, take corrective action
