1. Why Backyard Chickens? 🐔💚

Keeping backyard chickens offers multiple benefits:

• Fresh eggs daily: Delicious, nutritious, and traceable.
• Education & family bonding: Great for kids to learn responsibility, science, biology.
• Pest control & soil improvement: Chickens eat bugs, aerate soil, and contribute compost.
• Therapeutic value: Chickens are calm, charismatic—stress relief and joy in backyard living.

Plus—your flock will thrive on fresh foraged food around your garden, reducing feed costs! 🪱🌱

2. Choosing the Right Breeds 🐣

2.1 Egg Layers

• Rhode Island Red: Hardy, friendly, ~300 large brown eggs/year.
• Leghorn: Active layers of white eggs, alert and independent.
• Australorp: Quiet, gentle layer of ~250 eggs/year.

2.2 Breed for Families & Children

• Silkie: Small, fluffy, docile, gentle temperament.
• Orpington (Buff/Blue): Calm, affectionate, easy to handle.

2.3 Dual-Purpose & Heritage Breeds

• Plymouth Rock: Layers + friendly meat birds.
• Dorking: Long-lived, docile, heritage heirloom breed.

2.4 Bantams & Mini Flocks

• Bantam Cochins: Great for small spaces, gentle pets.
• Bantam Silkies: Compact, fluffy charmers.

Breeds to avoid for beginners: very flighty breeds (e.g., Campine), high maintenance show birds, noisy Gamefowl, or broody hens prone to hiding eggs.

3. Flock Size & Ideal Space 📏

3.1 Recommended Flock Size

Ideal backyard flocks are 4–8 hens—providing companionship, safety, and manageable care. Too small (1–2) can stress birds; too many requires more land and care.

3.2 Space Requirements

Indoor coop space: 2–4 sq ft per bird.

Outdoor run & free-range: Minimum 8–10 sq ft in run, plus 1,000+ sq ft garden space for daily roam.

3.3 Effective Rotation & Grazing

1. Rotate grazing areas weekly.
2. Use mobile chicken tractors (2–4 birds).
3. Rest pastures 4–6 weeks after seasons of use.

4. Coop & Run Design 🛠️

4.1 Coop Basics

• Ventilation: Roost-level vents 3–4 inches above perches.
• Roofing: Overhang for weather protection.
• Nesting boxes: One per 4 birds, cozy straw bedding.
• Roosts: Perch height 18–24 inches; thicker than hens’ toes.

4.2 Predator-Proofing

• Roof and perimeter cover: sturdy fencing above and around run.
• Secure doors: locks, hardware cloth, deadbolts.
• Night safety: automatic coop door recommended.

4.3 Bedding & Cleaning

Bedding choices: Pine shavings (dust-free), straw, hemp bedding, sand trays.

Deep litter method: Add 2" shavings, stir weekly, remove excess; fully clean 2–3 times/year.
