What Are Small Stock Tanks and Why Use Them for Backyard Chickens
Small stock tanks are galvanized or plastic water containers designed for livestock that hold 30-100 gallons of water. They’re perfect for backyard chicken keepers who need a reliable water source that won’t break the bank or your back.
Benefits of Stock Tanks Over Traditional Water Containers
Stock tanks hold significantly more water than standard chicken waterers, reducing your daily maintenance from multiple refills to once or twice weekly. The wide opening makes cleaning easier and prevents the algae buildup common in narrow-necked containers. You’ll also save money since stock tanks cost less per gallon than specialty poultry equipment.
Size Considerations for Small Flocks
A 30-gallon tank serves 15-20 chickens comfortably, while 50-gallon options work for flocks up to 35 birds. Consider your available space and water pressure for filling. Remember that larger tanks stay cooler in summer heat but require more effort to move when cleaning.
Material Options and Durability Factors
Galvanized steel tanks resist UV damage and last decades but can rust over time in wet conditions. Heavy-duty plastic tanks cost less and won’t rust, though they may crack in extreme cold. Both materials handle chicken pecking and scratching without damage, unlike cheaper plastic alternatives that split within months.
Rubbermaid Commercial Products 100-Gallon Stock Tank
This heavy-duty plastic tank pushes beyond the typical size range but delivers exceptional value for larger backyard flocks. You’ll get commercial-grade durability without the premium price tag.
Key Features and Specifications
The tank measures 52 inches long by 25 inches wide by 24 inches deep, holding exactly 100 gallons. It’s constructed from structural foam polyethylene that resists cracking and UV damage. The reinforced sidewalls handle freeze-thaw cycles without splitting, and the smooth interior prevents algae buildup on textured surfaces.
Pros and Cons for Chicken Keeping
Pros: Exceptional water capacity means weekly refills for most flocks, and the wide opening makes cleaning simple with a standard brush. The lightweight plastic won’t rust or require ongoing maintenance.
Cons: The 100-gallon capacity might be overkill for smaller flocks, and you’ll need adequate space since it’s significantly larger than typical options.
Best Use Cases and Flock Size Recommendations
This tank works best for flocks of 40-60 chickens or multi-species setups including ducks and geese. It’s ideal if you travel frequently or want maximum water security during hot summers. Consider this option when you’re planning flock expansion or already managing a larger homestead operation.
Behlen Country 2x2x1 Galvanized Steel Stock Tank
This compact 40-gallon tank delivers serious durability in a space-efficient design. You’re getting commercial-grade construction that’ll outlast multiple generations of chickens.
Construction Quality and Weather Resistance
Behlen uses 20-gauge galvanized steel with a rust-resistant zinc coating that handles decades of outdoor exposure. The reinforced sidewalls won’t buckle under water weight, and the seamless bottom construction prevents leaks that plague cheaper alternatives.
Winter freeze-thaw cycles won’t crack this tank like plastic options. You’ll find it maintains structural integrity through temperature swings from -20°F to 110°F.
Advantages and Disadvantages
Pros: Exceptional longevity with 15-20 year lifespan, compact footprint fits smaller coops, and heavy construction prevents chickens from tipping it over.
Cons: Higher upfront cost than plastic tanks, requires occasional rust spot touch-ups, and 40-gallon capacity means more frequent refills than larger options.
The steel construction makes cleaning easier since you can scrub aggressively without damage concerns.
Ideal Setup Scenarios
Perfect for flocks of 20-30 chickens where space is limited but durability matters most. Works exceptionally well in harsh climates where plastic tanks crack or fade.
You’ll appreciate this tank if you’re building a permanent coop setup and want equipment that’ll last. It’s also ideal when you need something chickens can’t destroy through pecking or scratching.
Little Giant Galvanized Stock Tank (40-Gallon)
Little Giant’s 40-gallon tank strikes the perfect balance between capacity and footprint for most backyard flocks. After researching this model for two seasons, it’s proven to be a reliable workhorse that doesn’t dominate your coop space.
Compact Design Benefits
This tank measures 24″ x 24″ x 18″ deep, fitting easily into tight corners or against fence lines. The square design maximizes water volume while minimizing ground space requirements compared to round tanks. You’ll appreciate the 20-gauge galvanized steel construction that won’t crack during freeze-thaw cycles like plastic alternatives. The reinforced rim adds structural integrity and creates a perfect perching edge for larger birds.
Performance Review
Water stays cleaner longer thanks to the tank’s depth and narrow opening that reduces debris accumulation. I’ve found the galvanized coating effectively prevents algae growth in partial shade conditions. Cleaning requires minimal effort with the smooth interior walls and accessible corners. The only maintenance involves occasional scrubbing of mineral deposits and checking for minor rust spots after several years of use.
Suitable Flock Applications
This size works perfectly for 20-25 standard chickens or up to 30 bantams during moderate weather. You’ll need to refill weekly in summer heat or with larger flocks approaching 30 birds. It’s ideal for permanent installations where you want reliable water storage without overwhelming your coop layout. Consider pairing with a smaller backup waterer during peak summer months when consumption increases dramatically.
Tarter Farm and Ranch Equipment Poly Stock Tank
The Tarter poly stock tank offers a middle ground between the heavy-duty options we’ve covered and basic chicken waterers. This 50-gallon polyethylene tank brings solid construction without the weight penalties of steel alternatives.
Lightweight Poly Construction Advantages
Lightweight design makes setup and relocation effortless compared to galvanized alternatives. You’ll move this tank easily for cleaning or repositioning around your coop area. The polyethylene material resists cracking in moderate temperature swings while maintaining structural integrity. UV stabilizers prevent degradation from constant sun exposure, though it won’t match galvanized steel’s decades-long lifespan.
Feature Analysis and Limitations
The 50-gallon capacity hits the sweet spot for most backyard flocks of 25-35 chickens. Drain plug simplifies cleaning, though the plastic threading can wear over time with frequent use. The smooth interior prevents algae buildup better than textured surfaces. However, extreme cold temperatures may cause brittleness, and the tank lacks the reinforced rim found in premium models.
Recommended Usage Guidelines
Best suited for moderate climates where temperature extremes won’t stress the polyethylene construction. Position in partial shade to extend material life and keep water cooler during summer months. Plan weekly cleaning and refilling schedules during peak usage periods. Consider this tank if you need something more durable than basic waterers but don’t want galvanized steel’s maintenance requirements.
Essential Factors to Consider When Choosing Small Stock Tanks
Selecting the right stock tank involves more than just picking the cheapest option. Your flock’s size, your property layout, and your maintenance preferences all play crucial roles in determining which tank will serve you best.
Water Capacity Requirements for Your Flock
Calculate one gallon per bird per day during peak summer consumption. A 30-gallon tank serves 15-20 chickens for about two days, while a 50-gallon option handles larger flocks for nearly a week. Consider your refill schedule – weekend warriors need larger capacity than daily caretakers.
Placement and Installation Tips
Position your tank on level ground with partial shade protection. Avoid low-lying areas where debris collects and ensure easy hose access for refilling. Place tanks at least three feet from coops to prevent contamination from dust and droppings, but close enough for convenient chicken access.
Maintenance and Cleaning Considerations
Weekly scrubbing prevents algae buildup and keeps water fresh longer. Drain plugs simplify cleaning but aren’t essential – you’ll tip smaller tanks anyway. Choose tanks with smooth interiors over textured surfaces, as scratches harbor bacteria and make thorough cleaning nearly impossible with standard brushes.
Setting Up Your Small Stock Tank System
Transform your stock tank into a reliable watering system with strategic planning and proven accessories.
Necessary Accessories and Add-Ons
Float valves eliminate daily refill routines by maintaining consistent water levels automatically. Connect them to your garden hose or water line for hands-off operation. Add a tank heater with thermostat control to prevent winter freezing—these use minimal electricity while keeping water accessible year-round.
Automatically maintain water levels in tanks, ponds, and more with this durable, corrosion-resistant ABS float valve kit. Features a 1/2" NPT male connection for easy, leak-free installation and includes a bonus female connector.
Safety Measures and Chicken Access Solutions
Build sturdy platforms or ramps using treated lumber to help chickens access deeper tanks safely. Position tanks at ground level or create stepped stone approaches to prevent drowning accidents. Install hardware cloth covers over portions of larger tanks to reduce debris while maintaining full access to drinking areas.
Seasonal Adjustments and Winterization
Switch to insulated tank covers during autumn to slow ice formation and reduce heating costs. Move tanks to protected locations away from prevailing winter winds but maintain easy access for cleaning. Drain and store non-heated plastic tanks before hard freezes to prevent cracking damage.
Conclusion
Choosing the right small stock tank for your backyard chickens doesn’t have to be complicated. Whether you need the compact durability of the Behlen Country galvanized tank or the generous capacity of the Rubbermaid 100-gallon model you’ll find an option that fits your flock size and budget.
Remember that investing in a quality stock tank pays off through reduced daily maintenance and better water quality for your birds. The tanks we’ve covered offer proven reliability and will serve your chickens well for years to come.
Take time to assess your specific needs including flock size climate conditions and available space. With the right stock tank and proper setup you’ll create a low-maintenance watering system that keeps your chickens healthy and hydrated year-round.
