From the 4th week to the 6th week, 320 Hailan layers were divided into groups at four levels randomly. Each group contained 16 replicates, and each replicate contained five layers. All layers were kept in pens with four different light intensity of 5, 10, 15 and 20lx, and then the feather pecking, feeding groveling, preening, foraging, drinking, standing and walking of them were observed. Results showed that light intensity had significant effects on the feather pecking of laying hens in brooding period; the occurrence of feather pecking, preening, foraging, drinking, standing and walking increased with the increase of light intensity, while the occurrence of feeding and groveling decreased.
