Here are the main differences between broiler houses and laying hen houses:

I. Purpose and Livestock Characteristics

Broiler Houses

Purpose: For raising broiler chickens, which are mainly for meat production.

Growth Rate: Broiler chickens grow very fast. They reach market weight in a relatively short time, usually around 6 - 8 weeks.

Space Requirements: They need enough space to move around, but considering their shorter growth cycle, the density can be relatively higher compared to laying hens in some cases.

Laying Hen Houses

Purpose: For raising hens for egg production.

Productivity: Laying hens start laying eggs at around 18 - 20 weeks of age and can lay eggs continuously for about a year or more.

Space Requirements: They need space for nesting boxes, perches, and enough room to move around to reduce stress, which is important for egg production.

II. Environmental Control

Broiler Houses

Temperature: Broiler chickens are sensitive to temperature. In the early stages, they need higher temperatures (around 32 - 35°C initially) and then the temperature is gradually reduced as they grow.

Ventilation: Good ventilation is crucial to remove ammonia and moisture produced by the high - density broiler population.

Laying Hen Houses

Temperature: Laying hens also need a suitable temperature range, generally around 18 - 24°C for optimal egg production.

Ventilation: Adequate ventilation is necessary to maintain air quality, especially considering the longer living time of laying hens and the potential for more waste accumulation over time.

III. Lighting

Broiler Houses

Lighting Schedule: Usually has a specific lighting program to promote growth. Longer photoperiods may be used in the early stages to encourage faster growth.

Intensity: The light intensity is adjusted according to the growth stage of the broilers.

Laying Hen Houses

Lighting Schedule: A carefully controlled lighting program is used to stimulate egg production. For example, increasing the day length during the non - laying season can help induce molting and restart egg production.

Intensity: The light intensity needs to be sufficient for the hens to see clearly for activities like foraging and nesting.

IV. Housing Structure

Broiler Houses

Flooring: Often use litter flooring, such as wood shavings or rice hulls, which need to be replaced regularly due to the high amount of manure produced by broilers.

Nesting Boxes: Not required as broilers are not laying eggs.

Laying Hen Houses

Flooring: Can be litter flooring or slatted flooring. Slatted flooring helps with manure removal and reduces contact with manure, which is beneficial for egg hygiene.

Nesting Boxes: Essential for hens to lay eggs. Usually, one nesting box is provided for every 4 - 6 hens.

V. Manure Management

Broiler Houses

Frequency: Manure needs to be removed more frequently because of the rapid growth and high - density stocking of broilers.

Utilization: Broiler manure is often used as fertilizer after proper composting.

Laying Hen Houses

Frequency: Manure removal frequency can be relatively lower depending on the flooring type, but still needs regular attention.

Utilization: Laying hen manure is also a good fertilizer source.
