found young pigeon

[maxinec]

Hello. I found a young pigeon (brown eyes, small yellow feathers on his head) several days ago in the street trying to dogde cars and a black cat. I took him home and my family has been feeding him thawed peas, wet puppy chow, and now some wild bird seed. He eats and drinks well.
Clearly, he is injured with several puncture wounds and a leg that may be broken. He doesn't like to move around a lot, and when he does he needs his wings and beak on the ground for balance. Is it possible for his leg to heal? What can I do to help him? Should I buy him a perch so that he learns to strengthen his one good leg in hopes that he can one day successfully hop around (I've seen seagulls do it quite well)? At what point should he be learning to fly? Should I do something to assist with that? What are our chances of being able to release him back into the wild (so to speak)?
Thank you!!!!
