Thanks for all the replies!! I have a BCM girl and a friend is getting rid of a Cukoo roo so.... Was just wondering. I have read that the egg from the off spring will be lighter if I go that route.
I would not do that cross. You will get 100% barred chicks with wild colors. The BCM might darken the eggs but still not worth that cross. I am sure you can find a roo for your girls. If not I will bring you one the next time I come to FL

To get darker eggs in the Cuckoos you would need to use SOLID Marans, either Blue or Black. That is on my slate.... if I can get some chicks with no GOLD leakage AND Feathered legs

Arielle, you want more Blue Cuckoos? I can save them for you next week..... I am setting the ones from this week. I have the hen with the MOST gold out of the pen now. Just PM if you do. I am hoping she will come soon to get the cuckoos. But I may set eggs till then.
