Wild robin with a broken wing?

If the wing is actually broken..it will not heal on it's own..the bird needs to go to a local wildlife rehab where they can either repair the wing, or humanely euthanize this bird. If this is just a young bird that has not yet learned to fly, you need to return it to where you found it as it's parents are very likely nearby caring for it. You can place it up in a tree or scrub for relatively safety from ground predators.

She is going to be pretty tramatized. She may eat earthworms that you can buy from a fishing store. Try not to handle her. She won't appreciate petting, at least not for quite some time. Be careful of diseases. Good luck. It is a lot of hard work.
