Ostriches farmed in Canada often have particular behavioral problems that are brought about by periods of extreme confinement during winter months. Although they still perform normal species specific behaviors such as twirling, kanteling, and kicking, abnormal behaviors become prominent when excessively confined. They include for all age groups of ostriches, feather-picking, behavioral stargazing, dietary indiscretion, pica, anorexia and adipsia, and aggression. These abnormal behaviors initiated by inadequate husbandry techniques, eventually become medical problems because of their severity.
在加拿大养殖的鸵鸟常常存在一些特定的行为问题，这些问题是由冬季极端圈养时期导致的。尽管它们仍会表现出正常的物种特定行为，如旋转、弯曲脖子和踢腿，但在过度圈养时异常行为就会凸显出来。这些异常行为在所有年龄段的鸵鸟中都有，包括拔羽毛、行为性凝视、饮食不当、异食癖、厌食和拒饮，以及攻击性。这些由饲养技术不当引发的异常行为，最终因其严重性而演变成医学问题。
