Here is what I did today to winterize my waterer, I use 5 gallon buckets for water and feed, galvanized tin pans, a heat lamp and extension cord. My waterer/feeder are on top of a pallet covered with hardware cloth. I put the tins on top of the buckets to keep the poop out of the water/food. I cut a hole in the hardware cloth large enough to place the bottom of the light bulb, the tins I got at Tractor Supply for $3.99 each I ran the extension cord under the pallets to keep the birds from pecking it and ran it through the chicken wire. The pan fit perfectly over the warming light with a 40 watt bulb. We are getting our first snow of the year today, hopefully it will work.
