Thank you dj1, that was my plan. There's lots of places in my yard that are great for worms, since they stay moist but not drenched and if I dig up just a little portion of ground there are many worms.

Would it be a good idea to maybe make a box like shape out of plywood or use a bucket and put dirt in it, with some worms, as winter is coming and I don't think worms will be as abundant as in spring/summer/fall and I'd like to have a plethora of worms for Pogo once he gets his appetite back.
