Building a Chicken Coop: The Complete Walkthrough

This guide covers building a chicken coop, rated a moderate task, typically taking 1–7 days.

Building a Chicken Coop is a genuinely useful skill for most homesteads. Here's the complete picture behind our one-page printable guide.

Predator-proof from the ground up

The single most important design factor is keeping predators out — that means secure latches, no gaps larger than a few centimetres, and ideally wire buried or turned outward at the base to stop digging predators.

Before You Start

Keep these points in mind:

  • Timber or another frame material
  • Weatherproof roofing
  • Predator-proof wire mesh (welded, not chicken wire, which is easily torn)
  • Roosting bars and nest boxes
  • Secure, predator-proof latches

How It's Done

Worth paying attention to:

  • 1. Plan for roughly 0.3–0.4m² of coop space per bird, plus an attached or separate run.
  • 2. Build a weatherproof frame with a sloped roof for water runoff.
  • 3. Fit welded wire mesh over any openings — chicken wire alone doesn't stop determined predators.
  • 4. Install roosting bars (higher than nest boxes, which birds prefer) and one nest box per 3–4 hens.
  • 5. Bury wire mesh 20–30cm around the base, or turn it outward in an L-shape, to stop digging predators.

When Things Go Wrong

Keep these points in mind:

  • Predator getting in despite precautions — check every gap and latch carefully; predators exploit surprisingly small weaknesses.
  • Poor ventilation causing damp, ammonia smell — ensure adequate airflow, especially high vents that don't create a direct draft on roosting birds.
  • Birds not using nest boxes — ensure nest boxes are lower and darker than roosting bars, which birds naturally prefer for sleeping.
  • Overheating in summer — ensure good shade and ventilation; a coop that's fine in winter can become a problem in summer without airflow.

Timing and Maintenance

Best time — build before bringing home birds, allowing time to get the design right without pressure. Duration — a basic coop can be built in a weekend; more elaborate designs take longer. Maintenance — clean regularly, check latches and mesh integrity periodically, especially after storms. Signs of success — a dry, secure, well-ventilated coop with no signs of predator attempts and birds using nest boxes and roosts as intended.
