That's a great idea, I never thought of that. I am raising my first batch of Wade BCMs, and am really looking forward to those eggs. I have a question that has probably been discussed before, but I can't find it in a search. I bought my BCMs straight run, and am going to have a few extra roos. I also have my own flock of cuckoos that I am working on the second generation. What would happen with a BCM over a cuckoo? I know it would be a mutt, but would the BCM help darken the cuckoo eggs? I keep my flocks separated, but I have room to add a pen to experiment. My gut is telling me to leave it be, but I was just wondering if anyone has ever tried this crossWhat color are the Marans eggs on the Marans egg color chart? It's impossible to tell with different lighting, monitors, etc. without one. We always have the chart in our egg photos.
It's helpful also to punch a hole in each egg color on the chart and put your egg behind the chart for most clear color matching, like this:
