Hi. Barron county wisconsin here. Cold now! Metal dog bowl on heated base isn't working. Freezing in 2-3 hours. I'm interested in your water solution. I've got 7 hens. Any advice appreciated.
First of all, I keep my feeder and waterer inside my coop, which I built big enough to house my chickens and all their feed and water 24/7. My waterer is not exposed to the cold wind and snow outside. It still gets down to -35F to -40F in the coop, but the waterer stays unfrozen.
I use a 3 gallon metal fount waterer....
That sits on top of a metal base heater. The base heater says it will keep water from freezing down to +10F, which as you know, is not very good for our northern states winters. However, since I have my waterer and base heater inside the coop, I can attest to the fact that it has kept my water ice free down to those -40F nights. Again, I suspect having the waterer inside the coop, not exposed to blowing wind or snow, is probably the magic ticket for me.
That sits on top of a concrete paver which keeps the base heater from sitting in the coop litter. I imagine the base heater is safe to use just sitting on the litter, but I liked the idea of having a more level base for the heater and also keeping it somewhat separated from the deep bedding in the coop.
I am familiar with the heated dog dishes, but did not think they would be good enough for my chickens in the winter. Those heated dog dishes are not rated for the low temps we get, and there is a lot of open water in that bowl to cool off fast. Believe me, if I thought I could save money with a heated dog dish, I would have considered it.
Having fresh water in the winter, and not having to refill water or tote it out to the chickens multiple times a day, was the deciding factor for me to invest in the metal waterer and base heater. 3 years ago, I think I paid around $80 for the set at our local Fleet store. The concrete paver was less than $2.00. I have never regretted spending that money. This will be my 4th winter with this setup and it has yet to fail me. If the heater base ever dies, I'll be back into town to buy another one before the day is out. I have 10 chickens, and I only need to refill my waterer about once every 10 days throughout the winter.
I try to save money everywhere I can, but when it came to fresh water, that is about the only area with my chickens that I invested in the best possible setup I could find. Perhaps nothing is more important to the health of the chickens than having fresh water available. Hope that helps. Good luck.
