We are into our third day of record heat. So far, I have added frozen water bottles to their waterers (idea from this site which works great). They do seem to pant less after drinking the cold water. THe hen house is in the shade and I am letting them free range in the shade under trees. Should I run a hose with water sown the hill to them as well? I also have a brooder house. The chicks are not sufffering as much, but we did put a screen door on their shed to improve ventilation. Any other ideas to help them out would be great.
