Why do the mularda pluck each other and remain almost completely without feathers? (Rimma)
Rimma, I hasten to note that among the mulard this behavior is common, so this breeze often worries many breeders. As the practice of breeding these birds, the main reason - the wrong diet or lack of protein. This type of duck has genetically increased development and growth. Therefore, for the necessary natural mass gain, the body requires a lot of protein. If there is a shortage - the bird makes up for the lack of their own.
The second reason is the daily routine and crowding. I emphasize especially that the mulardy are big ducks and capricious, therefore they require considerable space. Often a small room or failure to comply with the daily regime increases their aggression and the result is bare backs.
Regarding the recommendations, I advise you to add more protein supplements like bone meal or fish meal, minced meat, and powdered milk into grain masks. But you can give these protein products infrequently, about twice a week.
