In this video, the rim of the feeder pans is at the correct height. However, the available feeder space appears insufficient for birds of this size. This is clearly visible with the feeder on the right.

Most producers do not raise the feeder pans to the appropriate level; they remain too low, based on the belief that birds should be able to reach the feed easily. This is a misconception. When feeder pans are kept too low, birds scratch feed out into the litter. In addition, litter can contaminate the feed with bacteria (such as Clostridium perfringens) and coccidial oocysts, further compromising feed hygiene. The optimal height is achieved when the rim of the pan is level with the birds’ shoulders.

In broiler production, feeder space refers to the length or area of feeder equipment available for birds to eat comfortably without excessive competition. It is usually expressed as:

- Linear feeder space per bird (centimetres or inches per bird)
- Number of birds per feeder (for round or pan feeders)

Adequate feeder space is important because it:

- Ensures all broilers can consume sufficient feed
- Reduces competition and stress
- Promotes uniform growth
- Improves feed conversion and overall flock performance

The exact requirement depends on:

- Broiler age and body weight
- Feeder design
- Feeding programme
- Stocking density
- Management practices

Typical recommendations vary by feeder type and bird age, but common guidelines are approximately:

2.5–5 cm (1–2 inches) of linear feeder space per broiler
40–50 broilers per pan feeder, depending on feeder size and management system

Feeder space becomes particularly important when restricted or intermittent lighting programmes are used.
