Also in Massachusetts, woke up to frozen nipples, went to home depot and got this insulation to wrap my bucket. I cut a piece of the silver insulation and fit it into the bottom and marked and trimmed around the nipples then took a old bucket cut the bottom and top off, wrapped the bucket with the nipples with the silver insulation and slid the cut bucket over the insulation so nobody can peck at it.Also picked up a piece of foam insulation and marked and cut it out so it fits inside under the lid. In conjunction with the stock tank heater I have been using this should stop the freezing at -15 this has to help keep the heat in compared to what I had before.
