It was mentioned to me by someone with experience hatching French Black Copper Marans eggs in an incubator that FBCM eggs required a slightly higher humidity level do to the thickness of the shell. Any suggestions as to what the best humidity level for FBCM eggs in an incubator?

(I have a hen setting on 10 eggs but only 1 of 20 successfully hatched in my last "under the hen" attempt (the eggs were mailed to me, which could have been the problem). I have another batch of eggs from a different FBCM line and am "out of Broody Hens! LOL! So, this will be my first FBCM incubator hatching attempt.)

Thanks
 
Mine hatch great with "dry incubation". I try to keep the RH between 20 and 30%. During lockdown I aim for 80% or higher, but it often goes down to 65% during lockdown. All the eggs, including Welsummers, BBS Ameraucanas, Legbars and Barred Hollands get the same treatment, and all hatch well.

I have noticed that the dark eggs (Welsummers too) hatch a day after the light colored (CCL and BH) eggs. No idea why, it had me concerned the first few times, I thought they weren't gonna hatch, now I just try to be more patient.
 
Hey valleyhoneybee, do you sell any of your marans chicks?

I actually had not thought about it! LOL! I would be willing to. I have a pullet that is about 2 months old and the chicks that just hatched last week. I am not sure about shipping them (I have never sold any before and the French Black Copper Marans are certainly not plentiful around here!)!). I am in Plymouth New Hampshire. I am also getting 12 Marans eggs sometime this week that am going to incubator hatch. How many and what age are you looking for?

My husband said that one of the long time hatchers he talks to said he sprays his eggs down with warm water from a spay bottle when he opens his hatcher,has anyone out there ever tried this

this is due to a great incubator and hatcher my hunny bought me!!! But I haven't had a great deal of luck on my black copper eggs yet.
 
As a new "hatcher" of French Black Copper Marans I have talked with A LOT of people with FBCM. I had difficulty getting the eggs to hatch at first as well. What i have learned (& please remember I am NEW at FBCM hatching) is the eggs require slightly more humidity to hatch due to a slightly thicker membrane and shell (which, I am told, keeps more bacteria out of the egg than other types of chicken eggs). BUT, a word of caution, don't get too humidity happy or the chick will drown while attempting to hatch.
 
We have started a pretty good flock of Marans and I want to hatch a lot of FBC eggs
