How do you hand feed him? In my experience with igs with eating probs what works is you holding your ig in a firm but gentle way, grab some small chunk of a leafy green and gently coax it between the ig´s lips, the ig will chew on it and probly try to spit it out but you must try to keep the chunk of food in place, eventualy the chewing motion will begin and your ig will eat it, actualy often it only takes you to do this one or 2 times, if the igs is starving it can start to eat voluntarily just there. Im going to contradict a bit what Mike just said because in my experience young igs dont often are big fans of fruit, what they mainly recognize as food is leafy greens. My young igs never eated fruit on its own, only if it was among the rest of the food, and they only start to eat and apreciate it as half growns. As adults hell yes they love fruit, specialy figs, grapes and banana. Here is a list of food that should be its main diet: green beans, butter nut squash, turnip greens, collard greens, chycory greens, dandilions, water cress, mustard greens and rukula.
