That may work but you would only sanitize something coming in contact with the UV light very close to the source. Otherwise the UV is dispersed and has little or no effect.
I for one raised my chickens 'dirty' so to speak. they were in the dirt and grass immediately upon receiving them, no medicated food. I wanted them to get the antibodies built up to make them strong and able to beat any kind of bug that came about with a sledge hammer. Sterilizing stuff will only reduce their naturally developed immunity, the same as with people.
Just our philosophy though.
