Animal’s natural behaviors become restricted to confinement in housing facilities operated by human caretakers. For the purpose of, observing the animals to record research studies. Due to animals being in captivity, behavior patterns are abnormal compared to animals in the wild. In fact, orangutans, chimpanzees, and baboon’s social structure, social behavior, and other survival instincts are restricted to captivity. As a result, orangutans, chimpanzees, and baboons develop social and physical characteristics that jeopardize the animal welfare. In the wild, chimpanzee’s social groups are diverse. The chimpanzee’s communities range up to fifth to two hundred individuals. Chimpanzees’ grooming each other daily is an important social behavior.

The social deprivation and maternal separation in housing facilities are factors evoking abnormal behavior in chimpanzees. Abnormal behaviors are often implicitly or explicitly defined by an assumed relation to deprivation rearing or housing that lacked appropriate stimuli (Fritz et al., 1996). Southwest Foundation for Biomedical Research study of chimpanzee’s revealed factors in confined facilities corresponds to abnormal behavior in chimpanzees. Stressful procedures and the related effects of indoor single caging are probably to blame for increased stereotypies in captive chimpanzees on research protocols (Baker, 1996). Chimpanzees face living conditions that evoke patterns of abnormal behavior. Southwest Foundation for Biomedical Research study sampled 128 males and 140 females in a survey for results of presence or absence abnormalities in behavior. The data collected from Southwest Foundation for Biomedical Research was each chimpanzee evaluated showed specific abnormal behavior. The behaviors were categorize into five types of abnormal such as whole body movements, parts of body movements, self-directed behaviors, food- and feces-related behaviors, and group-related behavior. Self-directed behaviors have been reported to be higher in individually housed chimpanzees compared with group-housed chimpanzees (Brent et al.,
