After reading all the info on Marans and their famous egg color, I got to thinking (yes, that is dangerous). Has anyone tried breeding RIR for darker egg color? I thought I might try for fun to see how it would go. I currently have production birds and they are pretty nice layers, however have noticed that some eggs are darker than others. Would taking the darker eggs to set, hatch, raise, cull/keep and then repeat? Selection for darker eggs and once grown, correct conformation/coloring? Has anyone ever tried this? and if so, what were the results?
