I have tried to hatch Copper Marans eggs 4 times now. I have a silky sitting on 3 BLC marans eggs now for 22 days and there is no sign of hatching yet. She is so determined to hatch these and is a real good sitter. My previous attempts have been in an incubator twice and under broodies and I have never hatched a Marans yet. Are they too hard to hatch? How do the rest of you get them to hatch? I would so like to have a few BCM but this buying them and not getting any is getting pretty expensive. What is the secret?
