Are you handy? Why not make one!
I picked up a feed scoop, from a farm tool supply store. Drilled lots off 1/4" holes and attached a metal rod with steel wire. Cost about $12 for the galvanized feed scoop. The metal rod was hanging around the house. But any hardware store will have
various options. It takes some time, but mine works great! Sorry I'd post a pic, but I'm at work now. Yeah, hard working boy! lol
