Hi, this is my first Summer with Chickens and it's hot here today! About 100 degrees. Not much breeze. My chickens have mostly shade. I froze a water bottle for them and put it out there, but they seem clueless- I put a shallow dish of ice cubes (which melted in about 3 minutes) and I hosed down part of the run. Fresh cool water and ice in the water...Anything else I can do for my poor hot gals? Will they be fine in the shade?
