My kids and I are new to raising chickens and are needing help determining the breed of these 3. They are all about 5 month old. The 2 hens have not starting laying yet, or at least that we can find. They are free to come and go from the coop in a very large yard so we are sill searching for signs of laying! Lol This is Roo. This is Marshmallow. This is Reba.
