I started my flock this spring and finally have hens laying. I would like to add more chicks in the spring but I am not sure which brown egg layers lay the best and the ones that lay good size eggs. I currently have BOs, Barred Rock, RIR, Austrolorps, Wyndottes,and Brahmas. I do have a RIR rooster and I was thinking of hatching some chicks, so maybe RIR chicks or maybe black sex links.. Advise please.
