Quick Answer: For most backyard keepers the Run Chicken T50 is the better automatic coop door of 2026 — its rechargeable battery lasts roughly 1–2 years between charges (versus about 6 months on the Omlet’s 4×AA cells, per each maker’s specs) and its one-piece aluminum guillotine door installs on almost any coop in minutes. Pick the Omlet Autodoor instead if you own an Omlet Eglu coop (it bolts straight on), prefer a horizontal sliding door, or want the control panel mounted separately from the door. Both cost about $180, both open and close on a light sensor or timer, and both have built-in safety sensors that stop the door on an obstruction. If you want the shortest answer: Run Chicken for battery life and universal fit, Omlet for Eglu owners and separate-panel flexibility.
An automatic coop door is the single best quality-of-life upgrade for a backyard flock — it lets your hens out at dawn and locks them in at dusk whether or not you’re home, which is exactly when predators come calling. Two doors dominate the buyer shortlists: the Run Chicken T50 and the Omlet Autodoor. They land at almost the same price and both do the core job well, so the right pick comes down to battery type, door style, coop compatibility, and how you want to control it. We put the two head to head on the specs that actually change your daily keeping.

The differences that decide it, by the numbers
- Battery life: ~1–2 years vs ~6 months. Run Chicken rates the T50’s rechargeable battery at up to 1 year in cold climates and 2 years in warm ones, while Omlet lists about 6 months from the Autodoor’s 4×AA cells. Over five years that’s a handful of recharges versus roughly ten battery swaps — the single biggest maintenance gap between them.
- Cold rating to -4°F (-20°C). Omlet publishes an operating floor of -4°F (-20°C) for the Autodoor; Run Chicken markets the T50’s aluminum body as weatherproof and cold-tested with the battery rated for about a year even in cold climates. Both are genuinely four-season doors — according to real-world testing by Chicken Fans, both brands rank among the most reliable automatic doors they’ve tested.
- Door footprint: 19.25 × 16.5 in. Omlet’s door and frame measure 19.25 × 2.25 × 16.5 inches and weigh 8.38 lb, and the control panel is a separate unit you can mount outside the coop so its light sensor still reads the sky. The Run Chicken T50 is an all-in-one guillotine unit, so there’s only one part to place.
- App vs button. New Run Chicken T50 units (2025+) drop the physical button and are set up and run through the Run-Chicken Bluetooth app; the Omlet keeps a physical control panel with buttons. If you’d rather not depend on a phone, that’s a point for Omlet.
Run Chicken T50 — best all-round pick
Run Chicken T50 Automatic Coop Door
- Rechargeable battery lasts roughly 1–2 years per charge — far fewer battery interventions than AA doors.
- Weatherproof aluminum guillotine door mounts on almost any wooden or DIY coop, ready to use out of the box.
- Light sensor opens ~20 min after sunrise and closes ~20 min after sunset; timer mode and safety sensors included.
- New units require the Bluetooth app — no physical button — which not everyone loves.
The T50 wins on the two things you deal with all year: power and installation. Its rechargeable battery means you’re not buying AAs twice a year, and the self-contained aluminum guillotine bolts onto essentially any coop opening. The light sensor tracks the seasons automatically — out 20 minutes after sunrise, in 20 minutes after sunset — and the built-in safety sensor stops the door if a bird is in the way. The one caveat is the app-only control on 2025-and-later units: reliable in practice, but a change of habit if you liked a physical button.
Omlet Autodoor — best for Eglu owners and separate-panel setups
Omlet Automatic Chicken Coop Door (Autodoor)
- Horizontal sliding aluminum door with a control panel you mount separately — handy when the doorway itself is shaded.
- Fits straight onto Omlet Eglu Cube and Eglu Pro coops, plus most wooden coops and barns.
- Light sensor and timer can run independently or together; rated to operate down to -4°F (-20°C).
- Runs on 4×AA for about 6 months (Smart version can be mains-powered).
The Omlet’s ace is integration and flexibility. If you keep chickens in an Eglu Cube or Eglu Pro, the Autodoor is purpose-built to fit with no bracketry guesswork. The separate control panel is genuinely useful too: mount the door where it needs to be and hang the panel where the light sensor can still see the sky, which solves the classic problem of a pop-hole tucked under a run roof. You’ll swap 4×AA batteries about twice a year, or step up to the Smart Autodoor for Wi-Fi and mains power. The horizontal slide is a matter of preference — some keepers find it less prone to snow-jamming than a vertical guillotine.
Which automatic coop door should you buy?
- Buy the Run Chicken T50 if you want the longest battery life, a universal fit on any coop, and don’t mind a phone app. It’s the lowest-fuss choice for the majority of backyard flocks.
- Buy the Omlet Autodoor if you own an Omlet Eglu, want a physical control panel, need to mount the panel away from a shaded doorway, or prefer a horizontal sliding door.
Whichever you choose, remember a door only secures one opening. See our full roundup of the best automatic chicken coop doors for more options, and harden the rest of the coop with ½-inch hardware cloth and a predator-proof coop. Round out a hands-off setup with an automatic feeder and a no-spill waterer.
The bottom line
At roughly the same $180 price, the Run Chicken T50 is the better default: its rechargeable battery outlasts the Omlet’s 4×AA cells by years, and its one-piece aluminum door fits any coop out of the box. The Omlet Autodoor earns its place for Eglu owners and anyone who wants a separately mounted control panel or a horizontal sliding door. Buy the Run Chicken for lowest maintenance; buy the Omlet for Eglu integration and control-panel flexibility.
