So, everything I've read has lead me to believe that you should keep your chicks on starter feed until 10 weeks or so then switch them to grower feed and then at 21 weeks and beyond layer feed. Well, yesterday a guy at TSC told me that my 14 week old chicks should still be on grower feed. They free range most of the day but I want them to be getting what they need. Can anyone shed some light on the subject?
