I was not even aware that Bev was working with the cuckoos. My copper blacks came from her and they are very nice birds, certainly worth the wait. My best hatch from Bev was 5 out of 18. Others have had as many as 13 out of 16. I have found that hatching marans is a bit different than hatching typical eggs, even the ones I set from my own birds. They do not dry down as quickly and can tend to have problems if they are not kept a bit drier. I believe that the extra layer of pigment somehow causes this. Incubating with other breeds can be a challenge and even though I have done it (even got a few in there now with some sebrights and pheasants) it is a real juggling act. I always prefer to set them alone. The only reason I am even dealing with it now is because it appears that I may have 5 roos out of 7 chicks from my last hatch.
The other thing to keep in mind is what shipping does to them. I bought some BLRW eggs from a good breeder that lives only one state away. She shipped 16 eggs, 11 developed to around day 18, and then 5 hatched out. I then ordered a second batch, received 16 eggs, 5 developed until around day 10 and I had a single chick hatch. When you ship eggs you just never know. During both of those settings I had eggs from different hens, both my own, and had 100% hatch rates. Was it the breeder's fault? - No. It is something that we all risk when dealing with shipped eggs.
