We recently purchased 6 Rhode Island red chicks that are about 4 weeks old now. We wanted them for egg laying and everything we read said they were good layers and docile. We are thinking about purchasing some adult birds to start our egg laying while the babies grow up. I found a local organic famer who raises Giant White Plymouth Rock hens. He states these are also docile and good egg layers. Would they coexist with our baby Reds or should we stick to the same breed?
