Criteria | Norms During Growth | Norms After Maturity | Trouble Shooting Checklist |
---|---|---|---|
Temperature
(At birds height) |
Under Brooders
Day Old – 1 week: |
Room Temperature
21-22°C (Bird’s comfort) |
Too High: pasty cloacas, spreading and flapping, crowding away from heat source
Too Low: feather ruffling, huddling and piling near heat source |
Ammonia (P.P.M.) | Maximum: 25 ppm (see next page) | Maximum: 25 ppm | Too High: eye burns, higher incidence of breast blisters – leg problems |
Air Movement | 0.11 m3 per minute per kg live bird
or 2.75-3.0 cfm per kg live bird |
0.11 m3 per minute per kg live bird
or 2.75-3.0 cfm per Kg live bird |
Poor: high ammonia levels, wet, caked litter, Respiratory problems, increased foot problems, poor growth because of wet litter (see next page) |
Lighting | First 5 Days: 50 lux After 1 week: adequate light for feeding and activity |
Daylight Interval
Intensity must be 10 X greater than DARK interval to ensure good production levels |
Too High: cannibalism, flighty, nervous behaviour Too Low: poor intakes, poor growth and feed conversion |
Feeder Space (per bird) – ad lib Water Trough |
0.4 wks. – 3.5 cm 4-12 wks. – 8.0 cm |
12 weeks – mature
Feed – 10-12 cm |
Too Small: poor intakes, poor growth and starveouts |
Density – Floor or Cage Space
(per bird) |
Hens
0-4 weeks: 0.5 m2 Toms 0-4 weeks: 0.5 m2 |
Hens
12-16 weeks Toms 12-16 weeks |
Too Dense: feather picking, cannibalism, more injuries, more health problems, poorer carcasses or lower feed efficiency, wet litter – leg problems |
Handy Hints
Humans can detect the smell of ammonia at 7 p.p.m.
When human eyes are affected (watering/burning), ammonia levels are at least 20 p.p.m.

Figure 1. Guideline: Lamping Requirements for Poultry Chart. Shows Number of Square Feet per 60 Watt Bulb. Peter Nicholas, Energy Advisor – Agriculture, Ontario Hydro
Example (Real Barn):
A maintained light level of 20 lux may be achieved by using one standard 60W/120V incandescent bulb for every 200 square feet of floor space, or by using one long-life 60W/130V incandescent bulb for every 120 square feet of floor space in a dark barn.
Example (Research Lab):
A white clean room will have 40 lux with about one lamp per 280 square feet, or about 20 lux if one bulb per 560 square feet is used.
- Save Energy: Use 9 Watt to 11 Watt compact fluorescent lamps instead of 60 Watt/130 Volt incandescent bulbs
- Save Energy: Use 13 Watt to 15 Watt compact fluorescent lamps instead of 60 Watt/120 Volt incandescent bulbs
