With the rapid development of large-scale breeding industry, many livestock and poultry breeding companies have ignored the need for animals to express their nature in pursuit of economic benefits, which has led to serious animal welfare problems. For example, broilers are prone to feather pecking and fighting in a monotonous breeding environment, which increases the stress level, increases the mortality rate of broilers, and causes certain economic losses. According to the welfare standard requirements of the "HFAC Animal Welfare Standard-Broilers": free-range chickens must have at least 8 hours of outdoor time per day if climatic conditions permit, and pastured chickens must be outdoors for 6 hours per day if climatic conditions permit; according to the "Farm Animal Welfare-Broilers" standard requirements, when free-range, chickens should be provided with no less than 8m within 20m around the chicken house. 2 / 1000 shade sheds or artificial sheltered areas; therefore, it is very important to provide shelter for chickens that are active outdoors.
