Adult Male with head and mouth injury . . .

[johnhar]

I got this guy out of the road on saturday. He has a pretty good closed head injury and some damage to his mouth.
He is unstable on his feet, but seems to be more "with it" as time goes on. He just began drinking water from a syringe yesterday. Im certain he will survive.

Now I need to feed him. I need to feed him a liquid type diet for now - does anyone have suggestions? Right now my wife just said he ate some liquified strawberry and blackberry is that safe?

Thank you for any guidance you can provide -
