(a) Socially dependent birds, such as clutch-mates, must be housed in social groups, except where the attending veterinarian exempts an individual bird because of its health or condition, or in consideration of its well-being, or for specific management needs, or where such social grouping is not in accordance with a research proposal and the proposal has been approved by the research facility IACUC.

(b) Birds may not be housed with other animals, including members of their own species, unless they are compatible, do not prevent access to food, water, or shelter by individual animals, and are not known to be hazardous to the health and well-being of each other. Compatibility must be determined in accordance with generally accepted professional practices and by actual observations to ensure that the birds are, in fact, compatible.

(c) Birds that have or are suspected of having a contagious disease or communicable condition must be separated from healthy animals that are susceptible to the disease as directed by the attending veterinarian.
