I found an injured Pigeon today. It looks very young, not sure though. However, I took him home tried giving little water. It drank half a spoon of water. I don't know what happened to it. If its a broken leg or wing would it get better gradually ?tried giving some seeds. It won't eat and won't make any noise. what do I do?Also, I have to leave him at home all day because I have to go to work and there's no one else to take care of him.
