How to Use This Calculator
  1. Enter the chick age in days since hatch to get the target temperature for that specific day.
  2. Set the starting temperature in °F — 95°F at the brooder level is standard for day-old chicks.
  3. Adjust the reduction rate per week (°F) — 5°F per week is typical, tapering toward house ambient temperature.
  4. Review Target Temperature, Acceptable Low, and Acceptable High to set your brooder thermostats.
  5. Check Brooder Recommendation for guidance on when to switch from brooder rings to house-wide heating.
  6. Use Days Until Brooders Off to plan your heating schedule through the grow-out period.
