Should I feed the goose?

He's still around and he's apparently getting fed some bread, by people in the area, and seems to be getting quasi tame as he barly blinks when I'm near him, in fact a few times looking at me expectantly.  Not sure what would be good for him does bread work for a snow goose?   Feel sorry for him as he likly will be spending winter here unless he catches a ride with another flock, though the area he's in is rare for geese to land, only really seen the flock he was part of I think there.   I am concerned about aclemating him to humans too much, but at same time worried about how bad winter might be for him what you guys think?

he's a young snow goose, still having his juvenile feather pattern I believe.
