Integrating chickens into the garden: good idea... really?
The five hens from the Founding Garden have recently started laying. And with them, a question we often hear: "is it profitable, chickens?"
Bad question. Or at least: insufficient question.
First, the numbers — because they matter
Let's be honest: economically, the system holds up.
Current annual costs:
- Food → ~200 €
- Straw / bedding → ~65 €
- Infrastructure depreciation → ~100 €
- Total: ± 365 €/year
In return, a laying hen produces between 220 and 280 eggs per year. With five hens, that's about 1,200 eggs. Valued at 0.40–0.50 € each for quality farm eggs, we exceed 480–600 €. The margin is positive.
But stopping there is missing the point.
What chickens really do for the system
They close cycles
At the Founding Garden, the hens are not there to lay. They are there to transform what is useless into what the soil needs.
Peels, garden surplus, food scraps, plant biomass: everything that would go to the trash or compost first goes through them. This is not a detail. It is precisely what agroecology seeks to rebuild: short, local loops where nothing becomes waste.
Manure: the real wealth
A chicken produces between 40 and 60 kg of droppings per year. With five chickens, that's 200 to 300 kg of raw organic matter — rich in nitrogen, phosphorus, potassium — available locally, without purchase, without transport, without packaging.
Well managed (composting, reasonable incorporation), this manure can provide years of amendment. At a time when synthetic fertilizers are skyrocketing and dependence on external inputs is becoming a real risk, this autonomy has a value that no Excel spreadsheet can really capture.
Negative impacts exist. And they are serious.
This is where most articles on chickens in the garden stop thinking. Not here.
The soil, the first victim
A chicken scratches. It's its natural, irreducible behavior. On a large area, it's manageable. On a space that's too small, the consequences are quick and visible: destroyed vegetation cover, bare soil, local concentration of nitrogen that burns what remains, accelerated depletion of soil structure.
A minimum area of 5 m² per chicken is often cited. The reality on the ground is more like 10 to 20 m² for the system to remain ecologically viable over time. Below that, you create a desert.
They eat biodiversity
This point is rarely mentioned, and it's a surprising blind spot in discussions about "gardens with chickens."
A chicken is a very effective opportunistic predator. Its diet includes earthworms, larvae, beetles, various insects, and soil microfauna. In other words: exactly the organisms on which soil life, pollination, and natural pest control depend.
A system presented as ecological can therefore, depending on its configuration, actively reduce a part of the living beings it claims to protect. This is not a reason to not have chickens. It is a reason to think seriously about it beforehand.
Autonomy remains a relative myth
Last point, often carefully ignored in permaculture discussions: chickens eat grains. Corn. Seeds. Products mostly from outside the farm, often imported, with a real logistical footprint.
As long as we are not able to produce locally a significant part of their food, "raising chickens at home" does not mean "operating autonomously". It means: shifting a part of the dependency chain. It is not the same thing.
So, good or bad idea?
At Petites Terres, we try to avoid answers that feel good in the short term but oversimplify too much. Chickens are neither a miracle solution nor an ecological problem in themselves.
What they are: an tool. Powerful if well integrated, counterproductive if poorly sized.
It all depends on the available area, the real objectives of the system, the ability to manage the flows (manure, feed, pasture rotation) and an honesty about what can and cannot be produced by oneself.
At the Founding Garden, chickens are one element among others in a larger system. Not a showcase. Not an end goal. A link — useful precisely because we have accepted to also look at what it costs.
