I have 6 chicks who are inbetween 2 months and a little over 3 months. 4 are girls and 2 are boys. At what age can they start eating the layer pellet and game bird crumble feeds? Please let me know. This is the only thing holding me back from putting them with the rest of my adult flock. They need to move out soon because we have a younger batch who, in a few weeks, will have to move into where I have my 2-3 1/2 month olds are now. Again, please let me know at what age my chicks can start eating the layer pellet and game bird crumble feeds?
