I let my 7 week old chicks free range for the first time today and they loved it. They had to be closely supervised because we have a pair of red tail hawks that nest in our yard and they seemed very interested, but did not approach with my husband and me standing guard. The chicks had a great time eating bugs and plants and taking dirt baths. I really hated to put them back in their run. I wish I could let them free range all day, but safety first.
