Investors with relatively tight funds and some scale opt for chicken greenhouses because the construction is cheaper.

2. For those with unfixed breeding sites, such as free-range farming that might require relocation every one or two years, greenhouses can also be used due to their mobility.

However, from a technical perspective, greenhouse chicken farming has many drawbacks and is generally not recommended:

1. Greenhouses are often sealed with plastic film, resulting in poor ventilation. Humidity inside the greenhouse is difficult to control, and high humidity is a major taboo in chicken farming.

2. Many farmers choose greenhouse chicken farming for its affordability and convenience, so the ground is often earthen. This, combined with the poor ventilation of the greenhouse, leads to dampness inside, which can become muddy during rainy weather.

4. Greenhouses have poor insulation and lack structural stability.

The greenhouse frame is generally made of steel structures, which are readily available locally, similar to vegetable greenhouses. The height must allow for easy human access for management.

2. Greenhouse sealing materials: such as plastic film (commonly used), fireproof cotton (for insulation), film fastening lines, and load-bearing pillars inside the greenhouse. The ground should be paved with bricks or mesh to ensure dryness. If such conditions are not met, extra effort in management is necessary to keep the chicken coop as dry as possible. Install exhaust fans and use shading nets in summer to ensure temperatures do not exceed standards.
