Hello all! I am new to the site and researching what types of chickens might be best for my family. We are only allowed to have four hens per county restrictions. My kids are 3 and 6. We are only interested in the chickens as pets, for eggs and to help with my large garden. Any and all suggestions are appreciated! We live in Virginia and looking for hens that are docile enough for the kids to interact with. Also...should all four chicks be the same type of chicken or can I mix it up?
