Introduction to Poultry Hatchery Operations

Introduction to Poultry Hatchery Operations
Designed as a quick‑reference guide for students, new employees, and anyone interested in the basics of hatchery management.

1. What Is a Poultry Hatchery?

2. Core Components of a Hatchery

1. Egg Receiving & Storage

   • Receiving area – inspection, grading, and documentation of egg lot numbers.
   • Cold storage – 12‑15 °C, 70‑80 % relative humidity (RH) to preserve embryo viability (max 7 days).

2. Egg Handling & Preparation

   • Cleaning – dry brushing or low‑pressure air; avoid washing unless required.
   • Candling – detection of infertile or dead embryos before incubation.

3. Incubation System

   • Set‑up incubators – usually forced‑air (single‑stage) or multi‑stage units.
   • Temperature – 37.5 °C (99.5 °F) for most species.
   • Relative humidity – 55‑60 % (days 1‑17), 65‑70 % during hatching period (days 18‑21).
   • Turning – 45‑60 turns per day until day 18 (to prevent adhesion of embryo to membrane).

4. Hatching Process

   • Transfer to hatchers – usually on day 18; eggs placed in trays with proper airflow.
   • Hatch window – 21 ± 2 days for chickens; monitor for “pipped” and fully hatched chicks.

5. Post‑Hatch Handling

   • Drying & cooling – 30‑45 min in a cooling area (≈ 32 °C, 70 % RH) to reduce chick temperature.
   • Vaccination & tagging – according to species‑specific health programs.
   • Grading & packaging – sort by weight, sex (if sex‑linked), and health status; pack in breathable containers.

6. Waste Management

   • Egg shells, chick waste, dead‑in‑shells – collected, sanitized, and either composted or disposed of per local regulations.
