O/T - Box Turtle diet

[my apologies for cross-posting this with triangle.gardens, but I know that
some of you have discussed turtle ponds, etc.]

Yesterday, I noticed a Box Turtle (I think that's what it was) next to one
of my raised beds. Actually, I nearly stepped on the poor guy, because I
wasn't expecting any surprises there!

The turtle seems to be missing one of its front legs. I don't know how this
affects its ability to move around, it's apparent that the turtle uses its
front legs to pull off pieces of food to eat -- when I put down a few
slices of melon, it used one front foot to hold down the melon while pulling
pieces off.

Anybody have any suggestions what I should do -- if anything -- to help
this turtle out? I say "if anything" because I'd hate to see the turtle
become dependent upon my putting down food for it under the hedge. I'm not
going to put it in a cage, nor am I going to relocate it if I can help it,
because right now it's safe from my own dogs (and other dogs), and there are
lots of places for it to find cover.
