98 % of
Migros chickens
are fast-growing
breeds
— like Ross 308.
These so-called «Frankenchickens» go from chick to 2.5-kilo slaughter weight in 35 days. Their bones, hearts and lungs are not built for that speed. Less than one fifth of the birds can still walk normally on slaughter day. Migros advertises Swiss origin and animal-friendly farming.

«Young chickens that can barely stay on their feet, flailing helplessly on their backs in the litter.» That is the condition captured in footage from a Micarna farm (Migros). The Observatoire du spécisme and Tier im Fokus have therefore filed a complaint with the FSVO: alleged violation of the ban on torture breeding (Art. 10 of the Swiss Animal Welfare Act).
↗ Background · Observatoire article (DE)In March 2026, Migros announced a switch of its Optigal brand to slower-growing breeds.
But:
- Only 1 of 6 ECC criteria is addressed; the others remain non-binding.
- Imports remain exempt.
- Swiss farmers shoulder the cost, while Migros keeps selling lower-standard imports on the side.
