A small bird with a very bad mother.
Think of it, an egg can't climb onto a wall so, his mother must have laid him there. And then, she just abandoned him. Or, worse yet, she pushed him off the wall after laying him. Either way, children's services should have been called. At the very least, this was an incidence of gross neglect resulting in devastating injury. But, then again, if they had called in a physician instead of all the king's horses and men................well. who knows. It just sounds like the whole situation was mishandled from the get-go. And, where was the father when all this was going on?
