I have an old bathtub with varying soils, Rabbit and 'other' Litter mixed in with a lot of Coffee grounds.
Winter was cold this year.
I saw 11 Robins in my yard one warm day last week. Getting Worms of some kind.
But not one Robin went to my worm Bed!:p

I wonder if I'm out of the worm business? Do they know more than I do about raising worms?

I dont want to go digging out there, it's too cold yet. I wonder if there's a miracle food I can dump in that Tub to bring them back?
