If you can find the nest put it back, the mother will still accept it.
Robins are a softbill so they wont eat seeds. Feed them insects, grubs,
worms, berries, fruits, and moistened myna bird pellets. Dont give them
water cause they might aspirate, instead use foods with high moisture
content. Then it should be released when it can fly.
