Dietary supplements for caged birds are designed to complement a bird’s diet and mimic what their diet may have been like in the wild. Supplements are often used to maintain a bird’s protein and vitamin intake during moulting, bringing birds into breeding condition, improving egg production or supporting weaned chicks. Supplements such as Soluvet, Moulting Aid, Breeding Aid, Vetafarm Probiotic and Calcivet are the most popular with bird breeders.
