Plan Your Backyard Chicken Flock
Backyard chickens require more planning than most people expect — space requirements, feed costs, and egg production all scale with flock size. The standard coop allowance is 4 square feet per bird inside the coop and 10 square feet per bird in the outdoor run. A flock of 6 hens needs at minimum a 4x6 foot coop (24 sq ft) with a 60 sq ft run. Get the coop too small and you'll see feather picking, aggression, and disease — all problems that proper spacing prevents.
Coop Sizing and Setup
Start with the Chicken Coop Calculator to determine the minimum floor space, nesting box count, and roosting bar length for your desired flock size. One nesting box per 4-5 hens is standard — a 6-hen flock needs 2 boxes. Roosting bars should provide at least 8-12 inches of space per bird, placed 18-24 inches off the ground and above the nesting boxes so hens roost rather than sleep in the boxes. For the surrounding yard, the Sod Calculator helps you estimate how much grass or sod you need for the run area, and the Tree Spacing Calculator assists with planting shade trees that protect the run from summer heat — chickens overheat easily above 90°F.
Feed Costs and Management
The Backyard Chicken Feed Calculator estimates daily and monthly feed quantities based on flock size and hen stage. Laying hens consume approximately 1/4 pound of feed per bird per day — a 6-hen flock eats 1.5 lbs daily, or about 45 lbs per month. A 50-lb bag of layer pellets costs $15-20 at feed stores, meaning feed costs run roughly $15-20 per month for 6 hens. Supplemental scratch grains, oyster shell for calcium, and grit add another $5-8 per month.
Egg Production Planning
The Egg Production Estimator forecasts weekly egg output based on breed, hen age, and season. A healthy Rhode Island Red or Barred Rock in her first two years of laying produces 250-300 eggs per year — about 5-6 eggs per week. Production drops 20-30% in years 3-4 and continues declining. Hens also slow production in winter (short days) and during molt (typically fall). A 6-hen flock at peak production yields 25-35 eggs per week — more than most households need, making surplus eggs easy to share or sell locally.
Frequently Asked Questions
How much space does each chicken need in a coop?
The standard recommendation is 4 square feet of floor space per bird inside the coop, and 10 square feet per bird in the outdoor run. For large breeds like Brahmas or Jersey Giants, increase to 5-6 sq ft per bird. Bantam breeds can manage with 2-3 sq ft per bird. Crowded coops lead to feather picking, increased disease pressure, and stress — always err toward more space rather than less.
How much does it cost to feed backyard chickens per month?
A laying hen eats approximately 1/4 lb of feed per day. A 50-lb bag of layer pellets covers 6 hens for about 33 days. At $15-20 per bag, feed costs run $15-20 per month for 6 hens. Add $3-5 for oyster shell (calcium supplement) and $2-3 for grit, and total monthly cost is typically $20-28 for a 6-hen flock. This is often offset by egg production — 25-30 eggs per week at $3-4 per dozen has a market value of $9-12 per week.
How many eggs can I expect from backyard chickens?
High-production breeds like Leghorns (280-320 eggs/year) and Rhode Island Reds (250-280 eggs/year) are the most prolific. Dual-purpose breeds like Plymouth Rocks produce 200-250 eggs/year. Heritage breeds and ornamental breeds typically produce 100-150 eggs/year. Production peaks in year 1-2, drops 20-30% in year 3-4, and continues declining. A 6-hen flock of good laying breeds at peak production yields 4-6 dozen eggs per week.
