What a henhouse is and why it matters

Definition and Purpose

A henhouse is the birds’ bedroom, buffet, and safe room rolled into one. It keeps hens dry, calm, and out of reach from prowling predators while giving you a clean, convenient place to gather eggs.

Great coops balance shelter, sanitation, and safety. When those three sing in tune, birds stay productive and you spend less time chasing problems.

• Roosts for sleeping off the ground.
• Nesting boxes for clean, uncracked eggs.
• Ventilation that moves moist air out without chilling birds.
• Secure doors and latches that raccoons can’t puzzle out.

Layout and design essentials

Layout and Design Essentials

Space, Air, Light

Plan about 3–5 ft² (0.3–0.5 m²) of indoor floor per standard hen, plus 10–20 ft² (0.9–1.8 m²) in the run. Perches: 8–10 in (20–25 cm) per bird, set higher than nest rims. One nest for every 3–4 hens, lined with dry bedding. Cross-vent up high; light at head height, not eye level.

• Roost geometry: rounded edges, 1.5–2 in wide to support toes.
• Nests: dim, quiet, easy to reach; sloped lids deter roosting.
• Flooring: solid, easy to rake; deep litter or mats both work.
• Access: human door for you, pop door for birds; both latch securely.
• Predator-proofing: 1/2 in hardware cloth, buried skirt 8–12 in around the run.

Tip: Keep feed and water just outside the sleeping area to cut moisture and crumbs that attract rodents.

Daily rhythms and weekly chores

Daily Rhythms and Weekly Chores

1. Sun-up: open the pop door, confirm bright eyes and normal gait, top up clean water.
2. Midday: collect eggs, stir litter to release ammonia, check shade and airflow.
3. Dusk: count heads on the perch, close and latch, remove any soiled nest bedding.

Weekly: scrub waterers, wipe roosts, refresh dust bath (sand + wood ash + a sprinkle of diatomaceous earth), and inspect latches.

• Tools that save time: stiff brush, bucket, scoop, spare bedding, headlamp.
• Signs to log: egg count, feed use, any odd behaviors.

Health, hygiene, and biosecurity

Health, Hygiene, and Biosecurity

Most flock issues start with dampness or crowding. Dry, roomy coops break that chain.

• Watch list: pale combs, ruffled feathers, tail down, weight loss, coughing, or diarrhea.
• External pests: red mites, lice; check under wings and at night with a light.
• Feet and keel: look for bumblefoot, bruising, or breastbone wear from narrow perches.

Biosecurity basics: quarantine newcomers 2 weeks, change boots before visiting other flocks, store feed in sealed bins, and fence off wild-bird attractants.

Cleaning cadence: spot-clean daily, refresh nests weekly, deep clean seasonally; keep it gentle-harsh fumes and birds don’t mix.

Seasons, snags, and smart fixes

Seasons, Snags, and Smart Fixes

Heat, Cold, and Light

In summer, shade the roof, push more air through the high vents, and float frozen water bottles in pans. In winter, block wind at roost height, keep bedding dry, and rely on ventilation over heaters; frostbite hates dryness.

• Slow laying? Provide 14–16 hours of light using a low-watt timer at dawn.
• Pecking or boredom? Add roost variety, hang a cabbage, or scatter scratch in deep litter.
• Soft shells? Offer free-choice oyster shell; check that hens aren’t sleeping in nests.
• Smell or ammonia? Reduce moisture, add dry carbon (shavings), and boost airflow.
• Predator probe marks? Upgrade latches, add a night lock, and extend the wire skirt.

1. After any scare, do a perimeter walk.
2. Re-secure doors and patch gaps immediately.
3. Log the time and weather-patterns reveal the culprit.

Keep it simple, keep it dry, and the henhouse will hum along like a well-tuned instrument.
