I have found SFHs to need a dry hatch and if you want to PM me I am happy to tell you what I do.I have 11 in an incubator and 5 under a broody hen. I am trying the dry incubation method for this breed. I have never used this method. In my last hatch of olive egger chicks, I had 5 die in the very last day or so. I am suspicious that I had the humidity too high and the air sac was too small
