Build a Predator-Proof Self-Locking Chicken Coop Door

If you're tired of manually locking your chicken coop door every night, I've got the perfect solution for you: a sliding, self-locking door that keeps predators at bay. This innovative design features a vertical door that slides with a simple tug of a string, conveniently located outside the coop. Once lowered, the door locks from the inside, making it impossible for predators to tamper with the lock. Additionally, the design prevents the door from being lifted externally, adding an extra layer of security.

## Materials and Tools

To build this door, you'll need a few materials like a Rubbermaid shelf, ClosetMaid shelf tracks, a robe hook, utility hinges, and some screws. Tools required include a jigsaw, drill, and table saw. Adjust the materials based on your coop's specific design and setup.

## Step-by-Step Construction

Begin by selecting the area inside your coop for the door. If a vertical support beam is present, use it; otherwise, install one using a 2x4. Measure and mark your doorway size, ensuring it's slightly smaller than the door to prevent external lifting. Cut the opening using a jigsaw.

Next, secure the shelf tracks to the vertical beam with screws, ensuring they are flush with the track. Insert the shelf and the second track, marking where the second vertical beam should go. Cut the shelf to be slightly taller than the opening and attach the door latch. Ensure the door slides smoothly in the track.

Install a piece of wood above the door hinge to ensure the latch hits it when in the locked position. Attach a counterweight to the door hinge to facilitate self-locking, or use a spring lock instead. Thread a string through eye hooks to control the door from a distance, and install a coat hook to secure the string during the day.

This design is inspired by a YouTube video and offers a practical, hands-free solution to keeping your flock safe from predators.
