Yes, get him some polyvisol and for his head get him some Vitamin E, immediately.. Only give him about a drop of the vitamin E, and within an hour you will see him getting his head up. The polyvisol is a liquid vitamin that will help him to get his strength back.
When you give him the vitamin E just put it in front of his beak let him drink it, don't force it down his throat, when you see that he got some take it away. Hold his head straight up when you do this, if he doesn't move his beak to drink it will just slide down. He doesn't need much just a little to get a jump start. You can get it anywhere.. Think about how a chicken drinks, they get the water and put there heads up to let it go down there throats, you want to mimick the same procedure. Just don't put his head down keep it up..
