So I am trying to figure out what the right chicken breeds to start with would be. We live in town on about a quarter acre and have a 6 foot privacy fence. We are hoping to keep hens for eggs and pets, and are thinking of getting 4 of them to start with. I am drawn to the Plymouth Rocks and Orps (standard size). Are these birds good breeds to keep together? What about 2 hens of each breed ordered and started together?
