Please stop buying a whole grain feed. You are not helping your birds get a complete balance diet by feeding them that. It will cause problems once they hit laying age. No doubt.Our chicks are almost 10 weeks...and I wanted to spoil them so I got Scratch & Peck Feeds...and now they're not a big fan of the crumblesso I mixed that with another starter as they go through the scratch and Peck so fast. So it lasts a lot longer! And they still go nuts for it!
