Quote: I think a lot of the folks in AZ use them. I put them up because of recommendations on this thread. The only fall back that I can see is you need to keep an eye on the wetness of your run. If it gets soggy and doesn't dry out on a regular basis, it stinks more and can lead to fungus/mildew/mold problems. When I first put them up, I had one going through coop windows....cutting right through the coop. That was a bad idea. Soggy bedding is really nasty. Now they are in a shady area in the run.
Mine free range during the day so I have a shaded area that I put one in. It makes puddles in the dirt/mud (which they drink from) and they go in the shade, stand in the mister & get soggy.
