Hello, I found a baby pigeon which I assume to be 20 or so days old. He does not use it's legs, has to walk with his wings. I have inspected the legs and they don't respond to anything, I wonder if they are broken. Also, when I try to feed him he squeaks, opens his wings and beaks the palm of my hand I don't know what that means. Please, I don't know how to take care of him and I want to save him. Someone help me please.
