Mine are laying before they were expected to by a month, and they haven't gotten fat. They are eating Layena feed which has extra calcium, and their favorite treats are watermelon, cantaloupe and tomatoes. They will eat romaine lettuce, but it doesn't cause the excitement of juicy fruits. Easiest way to get them back in the run after they've been loose in the yard. Show up with a tomato cut in half and call them. They surround me so fast if I'm in sandals I have to worry about my toes. Whatever bugs they get they catch themselves.
