I am a Newbie, but I waited until they had their feathers. I read somewhere not to give them any treats until they got all their feathers because it gives them the runs. Once they got all their feathers I tried them on just small bits of greens, strawberries, apple, lettuce, green beans and just about anything else you can give to the grown ups. They dont like strawberries very much. Most of the rest they liked. But give them a worm or bug and look out they jump on it. Mine even went after a lizard when it got into the coop one time. They love chasing the flying bugs. Its fun watching them. Crickets are a hoot to watch them catch.
