I'm setting up a chicken coop. What are the recommended lighting colors for stimulating hen reproduction? Also, what are the minimum perch space requirements per hen, including horizontal spacing between perches and walls, and what are the potential risks associated with perches?
Navigate to the 'HOUSING FOR SMALL AND BACKYARD POULTRY FLOCKS' section. Click on the 'Lighting' sub-section (id: 153). Read the 'LIGHTING FOR SMALL AND BACKYARD POULTRY FLOCKS' article to identify recommendations for stimulating reproduction. Go back to the 'HOUSING FOR SMALL AND BACKYARD POULTRY FLOCKS' page. Click on the 'Perches' sub-section (id: 155). Read the 'PERCHES IN HOUSING FOR SMALL AND BACKYARD POULTRY FLOCKS' article to identify minimum perch space requirements and potential risks. Synthesize the information from both articles to answer the questions.
State that orange-red light (long wavelengths) stimulates reproduction. State that the minimum perch space is 15 cm (about 6 inches) per hen under regular standards and 18 cm (about 7 inches) per hen under organic standards. State that there must be a minimum of 30 cm (about 12 inches) of horizontal space between perches and 20 cm (about 8 inches) between a perch and the wall. State that perches cannot have sharp edges. Identify potential risks of using perches, such as increased keel injuries due to misjudged landings, skeletal damage (bone fractures, keel deformations), and fat pad lesions.
