Hi all. I have had my first backyard flock of americanas and rhode island reds for 1 week. They seem to be doing well. Can I give them anything for a treat such as fruits or veggies? They are eating chick starter, but I wanted to give them something special. Also, they are starting to scratch and peck at the bottom of their box. Should I put in a piece of sod? I read this somewhere online. I would appreciate the input of you veteran chicken mommies/daddies. Thanks!
