Ok, so I have all three of these breeds and I wand to stick with two of them, I want a broody so I can hatch eggs but also want a great layer. Also a hardy breed that can stand 100 to about 10 degrees. I'm considering just having RIR and Buffs. What are your thoughts. I would love to just have all three but I don't want mixed breeds. I will eventually separate them out when they go broody to hatch the chicks. Or go to one breed. What are other great hardy layers?
