Complete Cut List and Measurement Guide

A standard chicken nest box for medium or large breeds requires these panels:

Tip: Add ½–1 inch to the roof and entry overhang to prevent rainwater from entering.

Cut and Label All Panels

1. Measure Twice, Cut Once – Accuracy ensures a snug fit.
2. Mark cut lines clearly using a pencil and square.
3. Cut slowly to prevent splintering.
4. Sand edges smooth to protect your hens.
5. Pre-drill holes to avoid splitting wood.

Tip: Organize and label each piece before assembly to avoid confusion.

Step-by-Step Instructions to Build a Chicken Nest Box 

Now that your materials and measurements are ready, it’s time to start building. Follow these clear, practical steps to keep the process smooth.

Step 1: Assemble the Base and Sides

The foundation determines the box’s stability and hen safety.

What to Do:

• Attach the side panels to the base using exterior-grade screws.
• Make sure all edges are aligned and the box sits level on a flat surface.
• Check that panels are flush at all corners to prevent gaps where bedding or debris could escape.

Real Tip: Use clamps to hold panels steady while screwing them together for a square frame.

Safety Tips for Chickens:

• Ensure no screws protrude inside the box to prevent injuries.
• Sand all interior edges smooth to avoid cuts or splinters.

Step 2: Install Back and Front Panels

Adding the back and front panels completes the main enclosure.

What to Do:

• Secure the back panel to the base and sides with screws.
• Drill the entry hole in the front panel, 6–7 inches in diameter is ideal for standard hens.
• Attach the front panel to the sides and base, ensuring a snug fit.

Real Tip: Pre-drill holes before screwing to prevent wood from splitting, especially with pine or cedar.

Safety Tips for Chickens:

• Smooth the edges of the entry hole thoroughly.
• Avoid sharp corners or splinters near the entry to protect feet and feathers.

Step 3: Attach the Roof

The roof protects eggs and hens from weather and predators.

What to Do:

• Position the roof with a 1–2 inch overhang on the front and sides.
• If desired, attach hinges for a lift-top to make egg collection and cleaning easier.

Real Tip: Leave the cleanout side free of screws if using a hinged roof to avoid interfering with access later.

Safety Tips for Chickens:

• Ensure there are no gaps or loose panels that hens could get trapped in.
• Avoid nails or screws sticking up inside the box.

Step 4: Install the Entry Lip

The entry lip keeps bedding inside and makes access safer for hens.

What to Do:

• Attach a small wooden strip (1–2 inches high) beneath the entry hole.
• Secure with screws along the width of the opening.

Real Tip: Sand the lip edges smooth to prevent scratches or splinters when hens enter and exit.

Safety Tips for Chickens:

• Make sure the lip is sturdy and cannot break off easily.
• Avoid sharp edges or splinters that could injure feet or claws.

Step 5: Add Ventilation and Drainage

Proper airflow and drainage prevent moisture buildup, mold, and disease.

What to Do:

• Drill ½-inch holes near the top back corners of the box for ventilation.
• Drill 5–8 drainage holes in the floor to allow liquid to escape.

Real Tip: Slightly countersink drainage holes so bedding does not block them and water drains efficiently.

Safety Tips for Chickens:

• Ensure holes are small enough to prevent chicks from getting stuck.
• Smooth edges around all holes to prevent injuries.

Step 6: Add Bedding

Soft bedding cushions eggs and keeps hens comfortable.

What to Do:

• Add 4–6 inches of pine or cedar shavings inside the box.
• Never use sawdust; it can suffocate chicks and trap moisture.
• Avoid shredded paper, which absorbs moisture and molds quickly.

Real Tip: Keep bedding level and fluff it periodically to maintain insulation and cleanliness.

Safety Tips for Chickens:

• Ensure bedding is dry and clean to prevent mold and respiratory issues.
• Avoid materials that can tangle feathers or claws.

Step 8: Place the Box in the Coop

Correct placement encourages hens to use the box and stay safe.

What to Do:

• Mount the box 2–3 feet off the coop floor.
• Choose a quiet, dark corner away from high traffic.
• Ensure roosting perches don’t block access to the nest.

Real Tip: Adding a small ramp or perch helps younger or smaller hens enter safely.

Safety Tips for Chickens:

• Avoid placing the box near roosts where hens could get knocked over.
• Keep the floor under the box clean and dry to prevent slipping or injury.

DIY Nest Box Design Options

• Traditional wooden box: Durable and easy to customize.
• Bucket-style box: Repurposed 5-gallon buckets for space-saving.
• Tote bin box: Lightweight and portable.
• Crate-style box: Repurposed milk crates, economical.
• Roll-away box: Egg rolls to front tray for easy collection.

How to Encourage Hens to Use the Nest Box

• Add 4–6 inches of bedding (straw or wood shavings).
• Place fake eggs to encourage laying.
• Keep the area quiet and draft-free.
• Ensure boxes are dark and private.

Tip: Perches outside the box can make hens feel more secure.

Troubleshooting Common Nest Box Problems

Choosing the Best Location for Your Nest Box

Tip: Keep multiple boxes spaced apart to reduce competition and stress.

Predator Safety and Protection

• Use metal cone baffles or smooth metal poles to prevent climbing predators.
• Common predators: raccoons, snakes, squirrels, owls.
• Trim surrounding vegetation and avoid mounting near branches.

A well-built Chicken Nest Box is essential for your hens’ comfort and productivity. By using the right materials and design, you can create a safe, cozy space that encourages natural laying habits. With proper placement and care, your chickens will thrive in their new environment, ensuring healthier and happier birds.

FAQs

1. How many nest boxes do I need for 10 chickens?

For 10 chickens, you should have at least 3–4 nest boxes. This allows each hen to have a comfortable and private space to lay eggs, as chickens tend to prefer choosing their own spot. The general rule is one nest box for every 3–4 hens.

2. How often do you clean chicken nesting boxes?

Chicken nesting boxes should be cleaned at least once a week. Regular cleaning prevents the buildup of waste, keeps the nest hygienic, and reduces the risk of pests or unpleasant odors. If the box is heavily soiled or used frequently, cleaning more often may be necessary.

3. How often should I change chicken bedding?

Bedding should be changed every 1–2 weeks depending on how often the nest box is used. If the bedding becomes soiled or damp, it should be replaced sooner. Keeping the bedding clean is essential for maintaining a healthy and comfortable environment for your hens.

4. How can I prevent chickens from sleeping in the nest box?

To prevent chickens from sleeping in the nest box, ensure that the roosting bars are higher than the nest boxes. Chickens naturally prefer to sleep off the ground, so placing the roosting area in a more appealing position will encourage them to use it instead. You can also block access to the nest box at night or add a divider to make it less accessible.
