Lisses, Essonne, France

What was done

The commune of Lisses (Essonne, France, ~7,600 inhabitants), working with the local waste authority Siredom, ran an annual "200 poules pour réduire les déchets" operation — distributing two hens and a coop to 100 selected households each year. By 2018 it was running for the third consecutive year.

The key lesson: a difficult first year

Lisses is most useful as a case because its first-year assessment was openly described as mixed ("mitigé"). The Siredom communications officer identified the cause specifically: the hens were distributed at the wrong time of year. The pullets, aged 4–6 months, were still fragile, and handing them over in a cold, wet period worked against their health and settling-in. The commune learned from this and continued the operation in subsequent years.

What a replicating commune should know

• Timing of distribution is critical, and getting it wrong degrades the first year. Lisses' explicit finding: do not hand over young pullets (4–6 months, still fragile) in a cold, damp season. Distribute in milder weather so the hens establish well.
• A mixed first year is recoverable. Lisses did not abandon the scheme after a disappointing start — it adjusted and ran it again. A weak first round is a reason to fix the design, not to stop.
• A steady annual cadence works. Lisses settled into a repeatable yearly rhythm (100 households / 200 hens per year), a simple model for a single mid-sized commune.

Honest reading

Outcome recorded as partial: the first year was openly assessed as mixed due to a distribution-timing error, though the operation was corrected and sustained over multiple years. This case earns its place precisely because it documents a concrete, avoidable mistake — useful to any commune planning its distribution calendar.
