Chick crumbs (also known as Starter Crumbs) are a complete feed for newly hatched chicks, up to around 6 to 8 weeks of age. Chick crumbs can also be fed to duckings and goslings, provided the crumbs are not medicated. Grower pellets are designed to be fed as a follow on feed for chicks, ducklings and other young poultry, to support growth and development into adulthood.
