Ron, we got the same brand and kind as you only the hose is 1/4" and not 3/8". We hung it up in the run and put it on a battery ran timer. Is it an acquired taste because our flock doesn't seem to want to sit under them? :O
We also got them an automatic waterer (will take pics) and they are on and off using it still have the old one up too. They have been panting a lot and one night we got home and our Roos were roosting and panting and had droopy wings. We gave them fresh old water and they perked back up. Been putting "chick boost" in their water too. Is there anything else we can do to make them more comfy?
They do not need to hang out directly under them--The area cools off for a larger area then where the mist is. They will probably get used to it too.
Mine hated it when I tried to spray them with a hose last year.
