Mine free range most of the day, also, but we don't let them out until after 8am. They eat the commercial feed in the early am and bugs, grass, my flowers
the rest of the time. I throw out a few handfuls of scratch to them and also give them cottage cheese, watermelon, tomatos, leftover veggies, etc, so they are getting plenty to eat. My rooster, Rudy is getting real big! I am still waiting on my first egg...
