hi wildwood,
strange you should say about the spade bit. the first chicken we adopted ( it walked down my daughters driveway from no where ) goes berserk when you pick up a spade, so I throw a few spade fuls of soil into her run each day and she goes at it like its her last meal, digging in to it and grabbing worms and anything she can eat. she must have been someones pet because she likes being talked to,and picked up and stroked. and she lays eggs, so what a pet.!!! better than a dog, having to pick up poo, or a cat, ignoring you until feed time. got some more coming, rescued from a battery farm ( finished their laying days, ready to be incinerated ) they will lay a few eggs a week, and have a happy home, so we all win.
