In my experience babies aren't too interested in treats until 10-12 weeks, unless you are one to make your chickens pets. My current batch of babies finally approach treats with gusto. They are almost 3 months. A month ago they would stand there and give the treats the stink eye for several minutes before tasting, then eat it slowly. I finally got them to eat them eagerly with grapes, cut them into bit size pieces so they could just swallow them w/o pecking. Yogurt is easy for them to eat, and funny. The dip their beaks into it, add fruit the first time to encourage them to try it once they like fruit. I swear I can hear them slurp, but not really, I am half deaf. Cool fruit treats are great in the hot afternoon. I stop by the produce section of the market and have gotten permission to "trash pick" from their waste cans. Today netted 2 pkgs of melon pieces, bag of salad, 2 apples- small pickings. I have filled apple boxes on occasion when pickings are of things that will last a couple three days. Sure saves me money.
