I was tempted to use some of our sided compost. Anybody try that? Or perhaps even some of the unsifted stuff... I hate to use compost on birds, but I do have piles of it in our bins. I guess it could go back into the new compost pile after the birds are done scratching, rolling around and depositing nitrogen (poop) in it.The problem with yard dirt is that the yard is so unwilling to let go of it. A big plastic bag full of nice clean dirt ripped from the bosom of the earth, de-lumped and sieved by someone in possession of machinery is so worth the money.
