The temperatures were dropping below freezing and the animals weren't able to get any water. I could easily find a water heater for the goat's water because it is a big tub and finding a heater was simple. But finding ways to keep the three smaller water dishes for the chickens from freezing was looking too expensive, each new water dish was over $40 because they were new water dishes with built in water heaters.
And then I found information on another chicken blog that told me how to make a water heater for a few dollars...
Yes, I bought two tins from the store for a couple dollars. Then I took the light bulb piece from two lamps and attached them. I put them out there immediately to test them out, and sure enough that little 40 watt light bulb heats up the tin just enough to keep the water dish on top of it from freezing.
I also bought an outlet converter that only turns on when the temperature goes below 35 degrees, so the water heaters will all turn on when it gets too cold, but automatically turn off when the temperature warms up.
I felt like a genius this day :)
