I bought my chicks at a local hardware store. The clerk sold me a ginourmous bag of chick starter, way more than my three chicks will be able to eat before they need to switch over to grower feed. What can I do with the excess? Is there something I can mix it with to produce a feed that is appropriate for their next stage of growth? I am new to chickens and new to Backyard Chickens, but have enjoyed lurking for the past few weeks.
