Also is there any way to tell what age the chickens might be. We were told to Roo was 1 1/2 yr and the Hens were in their second season of laying. Not sure what that means. When we purchased the flock we got what we think are Black Copper Marans and we're not sure on the silver. We've had them for two weeks with no egg production. Is that normal or does anyone have any suggestions. We're feeding them Dumor 16% protein as well as scrath as directed in forums. Thanks for your help.
