Because my area (Houston,TX) has been in a severe drought for the last 9 mths, my hens have never seen rain. They went nuts yesterday when my area got 5 inches of rain in 4 hours!! (Praise the Lord, we needed it!) The hens just stood in the downpour. We ended up herding them into the coop, but they didn't want to go in. How silly they looked; drenched to the skin!!! What do "normal" chickens do when it rains?????
