Hi! I have two hens. One is a speckled sussex and the other is a partridge plymouth rock, both are about 5 months old. I have them free-rangin' around our yard and make chick-starter and cracked corn available for them in their coop. However I'm just about out of the starter/corn mix and I don't know what I should be buying for them! They haven't started laying yet so I want to make sure they are getting the proper nutrition to do so!
