We're so happy to offer this major upgrade to our top-selling Formex Snap Lock chicken coops. It's new, but only to us — it has been sold in the UK for the last few years to rave reviews.

When customers ask us what are the most important features any chicken coop can have, automatic doors are right at the top of the list. You'll never wake up in the middle of the night again, wondering if you forgot to close in your chickens, You won't have to sweat it if you go away for the weekend, work late, or want to sleep in on the weekends.

Why we love Swing-Open doors

We chose to offer a side-hinged complete door kit because they are considered more reliable than side-sliding doors. They offer more predator protection and convenience. Plus, it’s versatile for many different types of coops. You can choose to have your door open from the left or right: Just flip it around to the desired orientation.

Shipping: The Automatic Door Opener is expected to ship within one week after ordering. We will send your tracking number by email as soon as it's available, or you can look for it in the My Account area of our website.

Please carefully inspect your parts and ensure all items in the packing list are included. If you are missing any items, you must notify Hentronix within 15 days of arrival for replacements.
