We have Barr Rock too. I really like them. I also have 2 girls, 3 and 18 months, they are great little chicken farmers. Go out and help me feed and water their birds. It is great to meet you!
Welcome to BYC. Glad you decided to join our flock. Raising chickens is a wonderful experience for children. X2 on OrganicFarmWife's post; if you haven't done so already, definitely check out our Learning Center. There is lots of useful information there. Please feel free to ask any questions you may have. We are here to help in any way we can. Cheers.
