Anyone have these? What can I expect? Are they going to lay anything close to a dark shelled egg? Do they lay well and regular once they start laying? Do you like them? I had a lady tell me that I will end up with Barred Rocks and not the Cuckoo Marans if I ordered them from a hatchery. I have some coming later this Spring and I know I will love them no matter what, but would just like to be prepared now. TIA for your input.
