My duck is 6 month old but does not seem to be growing as can be seen in online videos. I live in city and I don't have a Backyard. I keep him in a cage and sometime I leave him in the house, roof, he roams around. I feed him boiled rice. I tried with wheat, some sort of chicken food grainy kind of thing but he doesn't eat those thing. As of now he eats only rice but the amount seems to be less. I tried with other things soya chunks which he was very fond of and enjoying but all of a sudden he stopped. So now he eats only boiled rice but it seems to be less in amount. Proper duck food does not seem to present here in India. I have attache one of his photo. Does he seem ok, if not kindly suggest.
