Fecal contamination of feed and water must be prevented. This means that feeders and waterers should be outside the pen whenever possible, and arranged so that fecal pellets can't fall in. Grain should be put in keyhole creep feeders rather than the open troughs that kids love to play and sleep in. Hay racks also must be covered to keep kids out. 11 Because oocysts have to sporulate to become infective, exposure can be reduced by cleaning the pens daily.
Slotted floors are helpful.
However, daily cleaning entails a vast amount of work and give disappointing results, if used alone. Ordinary disinfectants don't destroy oocysts. Leaking waterers should be fixed at once. Otherwise, the wet ground or floor around the water source is a perfect environment for oocyst sporulation. Small grassy ''exercise lots'' are also very dangerous and should not be used.
