Partridge are produced much like broiler chickens. Squab are the young offspring of pigeons. Pigeons produce 10 squab per breeding pair per year. Each squab weighs 0.45kg dressed weight. The pigeons eat high quality grain and partially digest it.
Squab production is labour intensive.
Silkies are bantam chickens. Silkies have a dressed weight of 0.74kg and convert 3.5kg feed per kg of body weight gain. They lay only 120 eggs a year when it is mature compared to 290 for a commercial laying chicken. The birds require 0.1m 2 of barn space per bird. Game birds are produced for their meat.
