(a) The diet for birds must be appropriate for the species, size, age, and condition of the bird. The food must be wholesome, palatable to the birds, and free of contamination. It must be of sufficient quantity and nutritive value to maintain a healthy condition and weight range of the bird and to meet its normal daily nutritional requirements. Birds must be fed at least once a day except as directed by the attending veterinarian, normal fasts, or other professionally accepted practices. If birds are maintained in group housing, measures appropriate for the species must be taken to ensure that all the birds receive a sufficient quantity of food.

(b) Food and, if used, food receptacles must be readily accessible to all the birds being fed. Food and any food receptacles must be located so as to minimize any risk of contamination by excreta, precipitation, and pests. Food receptacles and feeding areas must be kept clean and sanitized in accordance with § 3.158. Used food receptacles must be cleaned and sanitized before they can be used to provide food to birds maintained in a separate enclosure. Measures must be taken to ensure there is no molding, deterioration, contamination, or caking or undesirable wetting or freezing of food within or on food receptacles. Food receptacles must be made of a durable material that can be easily cleaned and sanitized or be replaceable when worn or soiled. Group-housed birds must have multiple food receptacles where needed to ensure that all birds have access to sufficient feed.
