Birds and doves that are housed, cared and fed properly get enough vitamins in their daily ration. Certainly when CéDé egg food is ingested during the breeding, moulting and rest periods according to the instructions for use.
Nevertheless, under certain circumstances, such as draughts, temperature fluctuations, disease, stress, flight season, moving to another environment (purchase of birds, bird show, etc.), the resistance of birds may be impaired.
In such circumstances, birds and doves have extra needs for vitamins that boost the metabolism and make them fit again.
