yeah, mine stink too. I have them in one of those commercial brooders so I just pull out the droppings drawer and change the paper everyday. Plus they have those feeders that attach to the sides of the brooder, so there is no wasted food. I'm kinda liking these brooders. I didn't think I would because I don't like raising chickens on a wire floor but wow is it much easier. Plus they don't have a problem with night and day since it's a heater not a light than keeps them warm. There are some real advantages to these.
