We added Silkies to our flock this year and had winterproofed their coop by wrapping it with plastic and putting a tarp over the roof. We are having one of those bitter cold weeks with temps below 0 with the wind. I went to check on them and noticed a few of them had wet crests and when I touched them the feather were frozen. I have moved them temporarily into the garage with a bit of heat to thaw their crests. Now my question is how do we prevent their crests from getting wet. I'm guessing it must be from drinking their water - they are slobs. Would it be ok to trim their crests and beards? Anyone have luck with a heated rabbit waterer?
