I have a spare, empty, sanitized incubator set up just so I can do a "Serama specific" hatch, geared with humidity and all just for serama eggs, not mixing them with marans, which need different humidity etc... plus I have a turner. No fan though, but have had a good number of eggs hatch with no fan, just not 100%. I look forward to test hatching for you and updating you on the results! YAY!
