When I went to clean out the brooder after removing the ducks, it was needed. Before that I had just been emptying their 16" X 16" water station (every third day) and putting fresh bedding on top every day...just a little, to cover any wet looking areas, which was pretty much the whole area. I only cleaned out the whole thing once for the 3 1/2 weeks the ducks spent in there and they were in the garage and it was not horribly smelly. But like I said, I did keep adding a fresh layer of bedding (pine shavings) on top daily. AND without the watering station (I do have pics, just scroll back) it would have been SO bad and I would have been changing that bedding every day (not kidding). In fact when they got older and drank more I could just hear the water dripping down into the water catch. And there was a lot of it. It was always over 1/2 full on the third day when it was time to empty it.
