Poussin
Poussin or coquelet in French cuisine is a young chicken that is less than 28 days old at slaughter.
A Poussin will weigh no more than 750 grams (26 oz), often much less.
It is sometimes also referred to as a spring chicken, but spring chickens are usually slightly larger at 750–850 grams (26–30 oz).
A Poussin would normally be served whole as a portion per person.
