my girls are 1 cochin, 9 years old. 1 gold sex link, 8 years old, 2 black sex links, 8 years old, 1 ameracauna, 8 years old, 3 Easter eggers, 5 years old, 2 cuckoo marans, 5 years old, and 1 barred rock, 5 years old. They are fed commercial feed 24/7, 20% protein. Brand changes often because of availability issues but always crumbles. They àre also fed wet mash daily, with mixed greens, apples, blueberries, scrambled eggs and crushed eggshells, topped with a thyme vinaigrette and mealworms. I bring this fresh food to them daily, topping off the diy hanging feeder my husband made while I'm there. They then go outside for all the bugs and grass they can find until evening, making sure they've ripped apart my compost pile properly before retiring for the night. When they are molting, I add a little game bird feed to their mash to up the protein a bit. And when it's winter I rush the food out to them while it's still warm.
