My friend is new to chickens... she has six 2-month-old pullets. She says that they're feeding them layer pellets mixed with chick feed. I told them that this is BAD. I told them that they should be feeding them grower (like me.) They said that no, grower is for MEAT BIRDS. We use the same feed store. I checked the bags: Starter- 0-8 weeks Grower- 8-20 weeks Layer- 20+ weeks I was right about what to feed. Is it true, though, that the calcuim is BAD for chicks as young as that? People have told me that before, just wanted to verify. Thanks.
