Okay, I've been looking this up and feel a bit confused, so I need folks to enlighten me. I currently have chicks ranging from 6 weeks to 15 or 16 weeks. They've been on chick starter and are doing fine. But I keep thinking they need to go off the chick food and onto an intermediate food before they start laying. I've looked at the feed store offerings and they have either Start and Grow (Purina) or Chick Starter/Grower (Nutrina). The other food available are either for layers or for meat birds. There is a food called flock feeder (Purina) that is basically the same as Meat Bird feeder from Nutrina. So, do I keep the chicks on chick starter/grower until they lay? Should I switch to Flock Feeder? I've been told to wait until 22 weeks or the first egg to switch to layer food. What would you suggest?
