Hello all! I have three 18 week olds and six 7 week olds. I'm in the process of integrating them (pic of them getting some free range time together) but wonder how to manage the food when they are all together. I know I need to switch the older ones to layer feed. Right now they are all eating starter/grower and I have egg shell available for the older ones ( they haven't started laying yet). Anyone had a similar situation and has any advice? Thank you in advance!
