How to Build Exterior Nesting Boxes for Chickens: A Step-by-Step Guide to Creating Cozy Nests for Your Chickens

Building exterior nesting boxes for chickens is a practical and rewarding DIY project that ensures egg collection is efficient, eggs are clean, and your flock remains comfortable. Quality nesting boxes mounted outside the coop allow you to gather eggs without entering the chicken area, minimizing disturbance and reducing mess. Here’s a step-by-step guide to building exterior nesting boxes, including considerations for materials, design, and placement for optimal results.

1. Plan the Design and Size

Standard nesting boxes should be about 12" x 12" x 12" per hen, though slightly larger boxes (up to 14") often give hens more comfort. Assess how many boxes you’ll need—a general rule is one box per 3-4 hens.

2. Choose Durable Materials

Exterior nesting boxes must withstand weather, so choose strong, rot-resistant wood (like cedar or treated pine) or weatherproof plastic. Use galvanized nails/screws and exterior-grade plywood.

3. Cut and Assemble the Pieces

Cut panels for the box’s back (attaches to the coop), sides, floor, roof (slanted for drainage), and front (with an entry hole or partial opening). Assemble the box, ensuring joints are secure and weather-sealed. A sloped roof discourages chickens from roosting on top.

4. Install Hinged Access and Ventilation

Mount the box so it attaches securely to the coop with exterior screws. Add a hinged, latching lid on the outside for easy egg collection. Drill small ventilation holes near the top, covered with mesh to prevent pests.

5. Line and Fill

Install a lip (2" high) at the entrance to keep bedding in place. Line the bottom with straw, pine shavings, or nesting pads for comfort and cleanliness.

6. Weatherproof the Structure

Use exterior paint or sealant on any wood, focus on seams, and apply weather stripping around lids to keep rain out. Position boxes facing away from prevailing winds and excessive sun for optimal temperature control.

As a designer, I always consider the balance of utility and aesthetic. For backyard chicken coops, integrating functional outdoor elements should enhance both the look and the usability of your structure—think harmonious proportions, color schemes that match your home or garden, and intuitive access. If you’re translating these ideas into other home projects or planning out your yard’s layout, consider leveraging a Home Designer tool to visualize and optimize your farmstead or exterior features before you build.

Tips 1:

Mount nesting boxes at least 18 inches above the ground to reduce threats from pests and moisture. Inspect the boxes weekly for cleanliness and structural integrity. If you have a large flock, stagger the placement of boxes to minimize crowding and encourage consistent egg laying.

FAQ

Q: How many nesting boxes do I need for my chickens?

A: Plan for one nesting box for every 3-4 hens to ensure all birds have comfortable laying space.

Q: What materials are best for weatherproof exterior nesting boxes?

A: Cedar, treated lumber, or heavy-duty plastic are ideal, combined with galvanized fasteners and exterior wood paints or sealants.

Q: Should the nesting box lid be slanted?

A: Yes, a slanted lid prevents water accumulation and discourages chickens from roosting on top.

Q: How can I keep bedding inside the nesting box?

A: Install a 2" high lip at the entrance to contain straw or shavings, even when hens enter and exit.

Q: Where should I position exterior nesting boxes on the coop?

A: Place them in a shaded, wind-protected spot that’s easy to access for daily egg collection and maintenance.
