At what age would you start feeding them mash? Mine are from 5-8 weeks old now.
One of our local mill only sells ground feed (mash) in a layer formula. Thus, it is chocked full of potentially harmful calcium for an adolescent bird. Feed is feed, whatever "shape" it comes in, it all begins as ground powder, then gets shaped into crumbles or pelletized. No layer formula feeds before you see the first egg drop, that's my view.
