Hi i'm currently raising my third group of baby chicks, well there more like teenager i guess. Anyway it seems to have slipped my mind the age you're supposed to stop feeding the chicks medicated crumble does anyone know? Thanks in advance.

My bag of Purina "Start N' Grow" medicated chick starter shows to use through week 18, and then switch to Layena grown-up chow.
