Every livestock owner knows the sound of a hammer on a frozen water tank at 6 a.m. Winter water is one of those chores that is easy to put off until the first hard freeze, and then it becomes the most important job on the farm. Cattle, sheep, goats, and chickens all need steady access to fresh, unfrozen water all winter long, and a little planning now saves a lot of ice chopping later.
Why Winter Water Matters
When pasture goes dormant, most animals switch to hay and dry feed, which carry far less moisture than fresh grass. That means they need to drink more, not less, just as their water sources start freezing over.
Water and feed go hand in hand. When livestock cannot drink enough, they eat less, and an animal that eats less has less energy to stay warm and hold condition through the cold months. That matters even more for bred cows, ewes, and does heading into winter and spring birthing season.
Snow is not a substitute. Animals cannot eat enough snow to meet their needs, and melting it inside the body burns energy they would rather use to stay warm.
For backyard flocks, water is just as important. Eggs are mostly water, and hens that go without, even for part of a day, can slow down or stop laying.
Choosing the Right Setup
Stock Tanks for Cattle, Sheep, and Goats
For larger tanks, a de-icer keeps a section of water open so animals can drink. There are a few styles to choose from:
- Floating de-icers. These sit on the water's surface and work well in most tanks. Our 1250-watt floating tank de-icer is thermostatically controlled and safe for plastic tanks.
- Sinking de-icers. These rest on the bottom of the tank. The 1500-watt sinking tank de-icer has a built-in guard for use in plastic tanks.
- Convertible de-icers. The 2-in-1 convertible de-icer switches between floating and submersible, so it can move with you between tanks.
- Drain plug de-icers. If you use Rubbermaid stock tanks, a drain plug de-icer for Rubbermaid tanks fits into the tank's drain hole. The heater stays at the bottom and the cord runs out the drain, away from curious mouths.
If you have a plastic tank, choose a de-icer that is labeled for plastic or has a protective guard. Larger tanks, windy spots, and colder locations call for higher wattage. Thermostatically controlled models only run when the water needs it, which helps with the electric bill.
Buckets for Smaller Groups
Buckets can be a good option for small herds/flocks of goats, sheep, calves, and stalled animals. The heated 20-quart flat back bucket hangs flush against a wall and keeps water ice-free down to -20°F. For several animals, the heated 16-gallon bucket holds more water and has an anti-chew cord. For containers up to 25 gallons, including plastic ones, a utility waterer de-icer is a simple add-on.
Waterers for Poultry
For chickens, ducks, and other poultry, a 3-gallon heated poultry waterer keeps water open down to -5°F, and its rounded top discourages birds from roosting on it. If you already have metal waterers, a galvanized heated poultry base sits underneath and keeps water from freezing down to 10°F. Heated bases are made for metal waterers only, so do not set a plastic waterer on one.
Safety First: Power and Cords
- Plug heaters into grounded, outdoor-rated outlets, ideally with GFCI protection.
- Run cords where animals cannot chew or pull on them. Many of our heated buckets have anti-chew cord protectors built in.
- Use extension cords only if they are rated for outdoor use, and avoid stringing several together.
- Check heaters every day. A heater that stops working lets water freeze, and one that malfunctions can overheat.
- If animals suddenly stop drinking from a heated tank, unplug the heater and check it. Even a small electrical tingle can keep animals away from the water.
- In the coop, keep cords and heated bases clear of bedding.
Daily Winter Water Checklist
- Check every water source at least once a day, and twice during a hard freeze.
- Keep tanks full enough that the de-icer stays covered, per its instructions.
- Skim out ice and debris so water stays clean and inviting. Goats in particular are picky about dirty water.
- Place tanks out of the wind when you can. A sheltered, sunny spot freezes less.
- Keep salt and mineral available, since they encourage animals to drink.
- Have a backup plan for power outages and frozen hydrants, like spare buckets and a way to haul water.

Frequently Asked Questions
Can livestock get enough water from eating snow?
No. Animals cannot eat enough snow to meet their daily water needs, and melting snow inside the body uses energy they need to stay warm. Always provide open, unfrozen water.
What's the difference between a floating and a sinking tank de-icer?
A floating de-icer sits on the surface of the water, and a sinking de-icer rests on the bottom of the tank. Both keep water open. Some models, like convertible de-icers, can be used either way.
Can I use a de-icer in a plastic stock tank?
Yes, as long as the de-icer is labeled for plastic tanks or has a protective guard. Drain plug de-icers made for Rubbermaid tanks are another good option for plastic.
Why are my animals not drinking from the heated tank?
Check the heater first. A malfunctioning heater can give off a small electrical tingle that keeps animals away. Dirty water and ice buildup can also discourage drinking.
How do I keep my chickens' water from freezing?
Use a heated poultry waterer, or set a metal waterer on a heated poultry base. Heated bases are made for metal waterers only.
