An IBC tote makes an excellent chicken coop — the HDPE outer cage provides a predator-resistant frame, the plastic inner bottle is easy to clean, and the overall structure is weatherproof without painting or sealing. A single 275-gallon tote comfortably houses 4–6 standard hens with proper ventilation and nesting boxes added.
This guide covers cutting the openings, installing ventilation, building nesting boxes inside, adding roosting bars, and setting up proper predator-proof latches.

Materials
Parts List
IBC Tote (275 gal)
The inner plastic bottle becomes the coop body. Cage frame provides structural support. Previous contents don't matter for coop use — just clean thoroughly.
$30–$100
Jigsaw + Metal Blade
For cutting the door opening and ventilation holes in both the plastic bottle and steel cage.
$0 (rent or own)
Hardware Cloth (1/2")
1/2-inch welded wire mesh for ventilation openings and the run door. Stronger than chicken wire — keeps out raccoons, weasels, and snakes.
$25–$60
Locking Latches (x3)
Raccoon-proof barrel bolt or carabiner latches. Standard handles won't stop a raccoon — use double-action latches.
$15–$30
Lumber for Roosts
2x2 pine or cedar, 18–20 inches long, sanded smooth. Hens need 8–10 inches of roosting bar per bird.
$10–$20
Nesting Box Material
Plywood or repurposed wooden crates. One 12"×12" nesting box per 3–4 hens. Can be built from scrap lumber.
$0–$40
Ventilation Grills
Plastic or aluminum louvered vents for the upper walls. Chickens need continuous fresh air but no cold drafts on the roost.
$15–$35
Exterior Paint (optional)
Light-colored exterior paint extends IBC tote lifespan by blocking UV. Not required but recommended for hot climates.
$15–$30

Planning
Layout Planning
A 275-gallon IBC tote is approximately 48" wide × 40" deep × 46" tall. The inner space comfortably houses 4–6 standard-size hens (allowing 4 sq ft of floor space per bird) or 8–10 bantam hens. Orient the tote so the door opening faces east or south — morning sun helps keep moisture down and encourages hens to lay earlier.
Interior layout from bottom to top:
- Floor level: bedding (straw, pine shavings), feeder, waterer access
- Mid-level: nesting boxes (one side wall)
- Upper level: roosting bars (opposite side from nesting boxes, as high as possible)
- Upper walls: ventilation openings (below the roofline)
The IBC cage frame is a strong asset — attach additional hardware cloth to the outside of the cage to extend a covered run area around the tote without needing separate framing.
Build Instructions
Step-by-Step Build
1
Mark and Cut the Door
Mark a door opening on the lower portion of one long side — approximately 18" wide × 22" tall, positioned so the bottom edge is 4–6 inches above the floor. Use an angle grinder with a cutting disc to cut the steel cage bars first, then a jigsaw with a plastic-cutting blade to cut the inner bottle. File or grind all cut edges smooth — sharp edges can injure hens. The cut piece from the inner bottle becomes your door panel, hinged back onto the cage frame with bolt-on hinges.
Cutting through the steel cage frame takes an angle grinder — a jigsaw won't cut the steel tubing. Rent one if needed; the cuts take about 30 minutes total.
2
Cut Ventilation Openings
Cut two ventilation openings high on opposite walls — ideally on the front and back of the tote, positioned above the roosting bar height. Each opening should be 6" × 12" minimum. Cover with 1/2-inch hardware cloth secured with staples or zip ties. Install adjustable louvered vents over the hardware cloth openings so you can reduce airflow in cold weather without removing the predator-proof mesh entirely.
Ventilation is the most important factor in chicken health. Ammonia from droppings accumulates in poorly ventilated coops and causes respiratory disease. When in doubt, add more vents.
3
Build and Install Nesting Boxes
Build simple box frames from 1/2-inch plywood — 12" × 12" × 12" per box. Mount them on one interior wall about 12–18 inches off the floor, lower than the roosting bars so hens prefer to sleep on the roost (not in the nesting boxes). Fill each box with 3–4 inches of straw or pine shavings. A lip along the front edge (2–3 inches high) keeps bedding from falling out. One nesting box serves 3–4 hens.
Position nesting boxes in the darkest corner of the coop — hens instinctively prefer to lay in dark, covered spots. A curtain of burlap over the front of the nesting boxes increases laying rates.
4
Install Roosting Bars
Mount 2×2 lumber horizontally across the interior, positioned as high as possible on the opposite wall from the nesting boxes. Round the top edges with sandpaper — hens grip with their entire foot and sharp edges cause foot injuries (bumblefoot). Space multiple roosts 12 inches apart vertically, stairstepped so upper hens don't drip on lower hens. Allow 8–10 inches of bar per bird.
Mount the roosts on brackets that allow easy removal for cleaning — accumulated droppings under the roost are the main source of ammonia and need regular removal.
5
Install Predator-Proof Latches
Raccoons can open standard barrel bolts and sliding latches with their dexterous hands. Install double-action latches that require two sequential movements to open — barrel bolts with a pin through the end, or carabiner-style latches threaded through the latch mechanism. Secure all three openings: the main door, the nesting box access (if you cut a separate exterior egg-collection door), and any other removable panels.
Test your latches with your own hands in the dark — if you fumble to open them, so will a raccoon. If you can open them easily, a raccoon can too.
6
Set Up the Floor and Bedding
The HDPE inner bottle floor is easy to clean but can be slippery. Add 4–6 inches of pine shavings or straw as bedding — it absorbs droppings, provides insulation, and gives hens material to scratch in. The "deep litter method" adds new bedding on top of old as the season progresses, letting it compost in place. Clean and replace all bedding at least twice per year (spring and fall).
The deep litter method generates a small amount of heat from composting, which helps in cold winter climates. It only works in a well-ventilated coop — in a poorly ventilated space, it just gets wet and ammonia-heavy.
Critical Detail
Ventilation Rules
Under-ventilation kills chickens
Respiratory disease from ammonia buildup is the #1 cause of flock death in backyard coops. The IBC tote is airtight by design — you must cut adequate ventilation. The rule of thumb: 1 sq ft of ventilation per 10 sq ft of floor space, minimum. For a 13 sq ft IBC coop floor, that's at least 1.3 sq ft of ventilation openings (about two 6"×16" vents).
Where to put vents: High on the walls, above the roost height, so cold air doesn't blow directly on sleeping birds. Cross-ventilation (vents on opposite walls) is more effective than vents on one side only.
Winter ventilation: Chickens tolerate cold well if they're dry and draft-free. Reduce vent opening size in winter but never close them completely. A humid, ammonia-heavy coop at 40°F is far more dangerous than a cold, well-ventilated coop at 20°F.
Security
Predator-Proofing Checklist
Raccoon Latches
Double-action latches on every door and opening. Raccoons open simple latches in seconds.
Hardware Cloth (not chicken wire)
Chicken wire has large openings that predators reach through. 1/2" hardware cloth stops everything.
Small Gap Check
Snakes and weasels enter through gaps as small as 1 inch. Inspect and seal all gaps with hardware cloth.
Apron Wire
Extend hardware cloth 12" along the ground apron around the base — prevents digging predators.
Frequently Asked Questions
A 275-gallon IBC tote has approximately 13 sq ft of floor space. At 4 sq ft per bird (recommended for confined flocks), that's 3–4 standard-size hens. With access to a run during the day, you can house 5–6 hens. Bantam chickens need only 2 sq ft each — up to 6–8 bantams work well in a single tote coop.
For a coop (not food production), the risk is much lower than for aquaponics or water storage. HDPE doesn't off-gas at normal temperatures. However, avoid totes that held pesticides, herbicides, or any compound labeled "danger" or "warning" — residues could harm chickens that peck at surfaces. Food-grade or water totes are safest. When in doubt, line the interior floor and walls with plywood.
Generally no — healthy chickens in a dry, well-bedded, draft-free coop tolerate temperatures well below 0°F without supplemental heat. HDPE provides some insulation. Most chicken deaths in winter are from respiratory disease from dampness, not from cold itself. If your temperatures regularly drop below -20°F, a low-wattage flat-panel radiant heater (not a heat lamp — these are fire hazards) can help keep the coop above freezing without creating a fire risk.
