I have tried every container, feeder and waterer, that I own for my turkey. He hefts his big turkey butt onto the galvanized or plastic containers and knocks them over constantly. I've tried using the black rubber bowls, but again, he THINKS he can stand on the side of it-of course, it flips and dumps the food. He wades through his water bowl like he's some kind of heron or something so it's always nasty. What are the best vessels for feeding and watering this maniac? Love this bird to pieces, but he is frustrating the crud out of me with this!
