Raising chickens for eggs can be a rewarding hobby and a profitable small-scale business. However, turning a profit requires careful planning and an understanding of your costs versus your revenue. This calculator is designed to help you estimate the potential profitability of your flock by breaking down the key financial components.
How to Use the Calculator
To get an accurate estimate, you'll need to provide a few key pieces of information about your operation:
Number of Laying Hens: The total count of hens in your flock that are actively laying eggs.
Avg. Eggs per Hen per Week: This varies by breed, age, and season. A good average for productive breeds like Leghorns or Rhode Island Reds is 4-6 eggs per week.
Sale Price per Dozen Eggs: Research local prices for farm-fresh eggs. This can range from $3 to $8 or more depending on your market.
Weekly Feed Cost per Hen: Feed is your biggest ongoing expense. An adult hen eats about 1.5 to 2 pounds of feed per week. Calculate the cost based on your local feed prices.
Other Weekly Costs: Include expenses like bedding (pine shavings, straw), supplements (oyster shell, grit), water, and any electricity for lighting or heating.
Total Startup Costs: This is the initial, one-time investment. Include the cost of the coop, fencing, feeders, waterers, and the chickens themselves.
Example Calculation
Let's imagine you're starting a small backyard flock with the following details:
Number of Laying Hens: 12
Avg. Eggs per Hen per Week: 5
Sale Price per Dozen Eggs: $6.00
Weekly Feed Cost per Hen: $1.25
Other Weekly Costs: $4.00 (for bedding)
Total Startup Costs: $750.00 (for a quality coop, run, and pullets)
Break-Even on Startup Costs: $750.00 / $11.00 per week ≈ 68 weeks. It would take about 68 weeks of selling eggs to pay off your initial investment.
Factors That Impact Profitability
While this calculator provides a solid baseline, remember that real-world results can vary. Factors like seasonal changes in egg production (hens lay less in winter), unexpected veterinary bills, loss of hens to predators, and fluctuations in feed prices can all affect your bottom line. The key to a successful egg business is to manage costs effectively, maximize production, and find a reliable market for your fresh, high-quality eggs.
