Found a escaped baby inidian hill mynah......now 8 months old.

i live in india (assam). my mom found and hand raised an baby indian hill myna (my dog saved it from crows). its 8 months old now n it toks too. but i live in a remote place. we dont have comercial bird food here. we feed it mostly homemade food or fruits.
i did a lot of research. found dat mynah should be fed a low iron diet.
can any one suggest a low iron food mix which can be made at hom.
Thanx a lot!!
