The presence of natural light through frosted glass is a practical solution to optimise light management in broiler houses and improve animal welfare. Frosted glass diffuses daylight evenly, reducing floor glare and local overheating. This supports a more uniform distribution of birds, limits crowding in shaded areas and reduces heat stress. Farmers report improved working comfort, calmer birds and better feed conversion ratio (FCR) due to more stable environmental conditions. This practice also helps meet welfare standards and supply chain requirements related to light exposure and atmosphere control. On farm, frosted glass can be installed in new poultry houses or integrated during renovation, ideally representing around 3% of usable floor area. According to 2021 technical data, average investment is about €17/m² (including windows, shading and installation), representing roughly 9% of the cost of a new house. Adjustable blinds are essential to control excessive light and maintain indoor temperatures around 20–25°C. Artificial lighting should be used before gradually opening blinds in the morning to avoid sudden light changes. Although installation requires planning and investment, the added value includes improved animal welfare, zootechnical parameters, reduced heat-related risks, better working conditions and enhanced farm reputation. This approach offers a balanced combination of welfare, performance and compliance benefits for broiler producers.
