Frequently asked questions
Do I have to eat four eggs a day?
No. The project’s name (Polish for “4 hens”) is not dietary advice. The calculator asks about your habits and your own assumptions. You can enter each household member’s portion or your weekly use. If you have particular health needs, agree the number of eggs with a doctor or dietitian.
Are home-grown eggs always cheaper?
No. What counts is the cost of feed, equipment, buying the hens, day-to-day upkeep and the number of eggs you actually use. We show the first-year cost separately. Surplus eggs are not automatic income. All starting amounts in the calculator are editable example assumptions.
How much space do I need?
By default the plan assumes 1 m² of indoor space and 4 m² of run per hen, so 20 m² in total for four hens. That is a starting point for planning, not a universal legal requirement or proof of good conditions. Dry ground, shade, ventilation, equipment and protection from predators matter too. A smaller layout needs a case-by-case assessment.
Do I need a rooster?
Hens lay eggs without a rooster. A rooster is only needed to fertilise eggs for hatching, not for collecting eggs to eat.

Why “4 eggs a day”?
