Hi, I'm looking for winter watering solutions. I bought a big electric plastic waterer but it won't fit in the door of my coop. I'm thinking of getting one of those Little Giant 125 WATT bases but I was trying not to spend the additional 40 buck for a metal waterer cause I have a new plastic one. I was thinking the base might just be about as warm as a light bulb, cause it couldn't be TOO hot or a chicken might burn on it- so is it possible that it wouldn't melt the plastic waterer.. or should I just buy the dang metal waterer? Thanks.
