I have 9 week old chicks. I have purchased feed from 3 different farm stores in the past few days. One gave me layer pellets which I changed after BYC forum informed they should not be on this yet. Another farm store gave me layer mash. I called a third store who told me that it is perfectly alright to give them layer feed at this point. The girl seems to know a lot about chickens and said she knows plenty of flocks who started on layer feed before laying and they are perfectly fine. Why do the stores tell me layer feed is okay at this point but no one on BYC seems to think so? I'm so confused!
