The pullet shut chicken door is an automatic coop door system made by the UK-based brand Pullet-Shut, designed to open at dawn and close at dusk using a built-in light sensor — no timers to adjust seasonally, no manual latching before bed. After running one on my 8-bird mixed flock for three years, I can say it genuinely does what it promises. The door panel itself is aluminum, lifts vertically on a track, and is sized at roughly 12 inches wide by 10 inches tall — big enough for standard breeds up to a heavy Sussex or Brahma, though you’ll want to measure your own opening first. This review covers the Pullet-Shut brand specifically, compares it to major competitors, and walks through installation, reliability, and the honest downsides.
Automatic Door Comparison: Pullet-Shut vs. Competitors
Before going deeper on Pullet-Shut specifically, here’s how the main options compare on specs and price (all prices approximate USD as of 2025):
| Brand | Drive Type | Trigger | Door Size | Price |
|---|---|---|---|---|
| Pullet-Shut Standard | Motor + belt | Light sensor | 12″ x 10″ | ~$170 |
| Pullet-Shut Premium | Motor + belt | Light sensor + timer | 12″ x 10″ | ~$210 |
| ChickenGuard Standard | Motor | Light sensor or timer | 10″ x 14″ | ~$150 |
| ChickenGuard Premium AX | Motor | Light + timer + app | 10″ x 14″ | ~$230 |
| Omlet Automatic Door | Motor | Light sensor | 11″ x 11″ | ~$180 |
Pullet-Shut sits in the mid-range price bracket. The Standard model is solid for most backyard flocks; the Premium adds a timer override useful in heavily wooded yards where ambient light behaves oddly.
What Is Pullet-Shut and How Does It Work?
The pullet-shut system operates on a light-sensing photocell that reads ambient lux levels. When light drops below a set threshold at dusk, the motor triggers and the door slides down into the closed position. At dawn, it reverses. No Wi-Fi required, no app, no subscription — which is one reason backyard keepers with older phones or rural internet appreciate it.
Key specs worth knowing before you buy:
- Power: 4 x AA batteries or optional 6V DC adapter (solar-compatible)
- Battery life: approximately 6-12 months on alkalines depending on climate
- Motor load limit: the unit can detect an obstruction (a bird in the doorway) and reverse — but this safety feature is not 100% foolproof; it’s a helpful backup, not a guarantee
- Operating temperature range: -4°F to 122°F (-20°C to 50°C), which covers most US and UK winters
- Warranty: 2 years
The pullet-shut door opener adjusts automatically to seasonal daylight shifts, which eliminates the twice-yearly timer juggling that drives keepers crazy with basic programmable units.
What to avoid: Don’t buy any light-sensor door — Pullet-Shut or otherwise — if your coop sits directly under a security light or flood lamp. The artificial light will confuse the sensor into keeping the door open all night. Either shield the sensor or choose a timer-based model instead.
How the Automatic Coop Door Installs
Installing the automatic coop door takes most people 30-60 minutes with basic hand tools. The kit ships with a track, motor unit, door panel, mounting hardware, and a short manual. You cut or route a slot in your coop wall to match the door dimensions, then bolt the track frame over the opening.
What I found during my own install:
- The aluminum panel is lightweight but not flimsy — it’s held up to three New England winters without warping
- The belt drive is quieter than the rack-and-pinion used by some competitors; my birds don’t startle when it moves
- Sensor positioning matters: mount it on the exterior, facing north if possible (in the Northern Hemisphere), away from direct morning sun hitting it at an angle
One honest downside: the included hardware is metric, and the manual is written for UK coop construction norms. A few mounting screws needed swapping for US builders working with imperial lumber. Minor, but worth knowing before you start.
The automatic coop door has also proven predator-resistant. Raccoons and foxes can’t lever it open once it’s seated. Hardware cloth on any surrounding gaps remains essential — the door handles the main opening, but a persistent weasel will find a gap in old coop boards that no door system will fix.
The Pullet-Shut Door Opener: Sensor Sensitivity and Adjustments
The pullet shut door opener includes a sensitivity dial on the motor unit. This matters more than most reviews mention. I initially had the sensitivity too high; the door was closing at 4:30 PM in October — earlier than my hens were reliably inside. Walking that dial back two notches solved it.
Adjustment points for the pullet shut door opener:
- Sensitivity dial: Low = closes later (lower light threshold); High = closes earlier
- Delay timer: Some Premium models add a close-delay (5-30 minutes after sensor triggers) — useful if your slowest hen is a Cochin who takes her time
- Manual override: A button on the unit lets you open or close on demand without resetting any programming
In my experience, the light sensor outperforms basic timers for year-round reliability. From late June to September, I don’t touch the unit. It shifts closing time gradually with the season, and my flock is never locked out or left exposed. From November through February, I’ll occasionally check that stragglers are inside before the door drops — old habits from manual latching days.
For a flock of 4-12 birds, the pullet shut door opener handles the standard opening size without modification. Jersey Giants and large Brahmas occasionally need the door opening enlarged slightly; the aluminum panel can be swapped for a wider custom-cut piece if your coop opening is non-standard.
Auto Chicken Door vs. Manual Latching: Is It Worth It?
Most keepers who switch to an auto chicken door don’t go back. The practical value isn’t just convenience — it’s consistency. A door that closes at the same light level every night, regardless of whether you’re home, traveling, or sick, reduces predation incidents meaningfully. The leading cause of flock losses is a door left open after dark, usually by accident.
The auto chicken door category has expanded in the last five years. Beyond Pullet-Shut and ChickenGuard, there are cheaper options in the $40-80 range on Amazon with no-name motors and thin plastic housings. I’ve seen those fail inside 18 months — stripped gears, sensors that drift, panels that warp and jam. The $150-230 tier where Pullet-Shut operates uses more durable motor assemblies and thicker aluminum.
For most backyard flocks in the US and UK, the auto chicken door pays for itself in reduced stress, not having to rush home by dusk, and avoiding that one night you forgot — which often turns into a significant loss.
Conclusion
The pullet shut chicken door is a well-built, light-sensing automatic door that outperforms basic timer units for year-round reliability and holds up in real weather. It isn’t the cheapest option, but the aluminum construction, obstruction-reversal safety feature, and no-subscription operation make it a sensible buy for anyone running a backyard flock of 4 or more birds. If you’re comparing the pullet shut chicken door against ChickenGuard or Omlet, the differences come down to door sizing and whether you want app connectivity — Pullet-Shut skips the app and keeps it simple, which suits most keepers just fine.

Frequently Asked Questions
Will the Pullet-Shut door close if a chicken is in the way?
The motor includes an obstruction-detection feature that triggers a reversal if resistance is felt. In practice, chickens rarely linger in the doorway at dusk — they roost once inside. The safety feature is a useful backup but shouldn’t be relied on as your primary safeguard. Train your flock to roost early by keeping feeding consistent.
Does the Pullet-Shut work in freezing temperatures?
The unit is rated to -4°F (-20°C), and the aluminum panel doesn’t warp in cold the way plastic alternatives do. In heavy snow, periodically check that drifts aren’t blocking the door track. Battery performance drops in extreme cold; switching to lithium AAs extends winter battery life significantly compared to standard alkalines.
How long do the batteries last?
Expect 6-12 months from a set of 4 AA alkaline batteries under normal use. The motor draws power only during opening and closing cycles — twice a day — so daily use is very low. Lithium batteries push that to the upper end of the range or beyond in cold climates.
Can I use the Pullet-Shut with a solar panel?
Yes. The unit accepts a 6V DC input, and several solar trickle-charge setups sold for trail cameras and garden equipment are compatible. A 1-2 watt panel with a small buffer battery keeps the unit running indefinitely without any battery swaps — a popular setup for remote coops without easy access.
What size opening does the standard Pullet-Shut door fit?
The standard aluminum panel covers a 12-inch wide by 10-inch tall opening. That’s adequate for most breeds including Rhode Island Reds, Plymouth Rocks, Wyandottes, and Orpingtons. Very large breeds — Jersey Giants, Brahmas, Cochins — may need the opening enlarged to 12 x 12 or 13 x 11 inches. Pullet-Shut sells replacement panels in alternate sizes for custom installs.
