My silkies are always doing something like that and have never had any adverse effects. I had two boys that would run around in the rain until they were soaked and I would have to dry them. If I didn't cage them, they were right back out in the rain even though they had a nice big insulated dog house.I have a chicken q: This morning I noticed the birds' waterer had frozen over, even though it's in a heated dog bowl. (The water in the dog bowl isn't frozen, and the waterer itself isn't frozen, there was just enough ice on top of the drinking surface to keep the birds from getting anything...and I suspect it was too thick for them to peck through.)
At any rate, I refreshed the water and it spilled out like a waterfall. One of my silkies immediately started drinking from the overflow and I couldn't help but notice her head getting wet. She doesn't have big wattles, but I can't help but wonder about her entire head. The earlobe, whatever. What should I do?
