摘要: Abstract The involvement of light in nest-site selection by domestic fowls was tested two strains laying hens at stages maturity. Individuals that were about to lay an egg isolated a pen and given choice sorts nest-box, one illuminated internally the other without illumination. Nearly all birds laid boxes provided, but their dark or conditions varied strongly with both strain Only four categories hen, those White Leghorn first egg, exhibited expected preference for nests. Birds derived from Rhode Island Reds more likely nests, which had previously been open pens showed greater nests than did naive individuals. These results suggest intensity is not fundamental factor influencing selection, it may nevertheless haveto be considered management hens.
