We just found a duckling on its own. We have him in a box and am heating him with a lamp for now. I have no idea if he's injured, just hatched, or what. I chopped up a hard boiled egg and have some water in with him, but beyond that, I don't know what to do from here. He is sitting but at times leans far back so he could be injured. Can anyone help as to what we do next or how to nurse him back to health if he's indeed injured? Thanks!
