I have a almost one month old penkin duckling.I let him outside with his brothers and sisters to swim.When i came back i noticed he was missing.It took me a while to find him.When i did he was lying down with blood on him and alot of feathers missing.I ran back inside and researched all i could.I gave him food and water wich he did not drink much of,then i put neosporin and any thing i could find in my first aid kit. I cleaned him off then applied more pain relief stuff. He slept in a box in my garage and this morning he ate and drank some. but he will not stand on one foot and nothing seems to be wrong with it. what should i do?
