I have an one year old muscovy drake that has been very listless for a few days, he does not want to walk much and does not shake his tail and hisses as he used to. His caruncles are loosing the red color and are turning greyish. From what I could find on the internet ,he could have anemia, since he free ranges and I feed him chicken scratch. I can not find any treatment options exept someone feeds their muscovies wet catfood and dog kibbles, which my drake does not want to eat. What should I feed him to get color back in his cheeks ?
