I done serama last year and the year before. I know what you mean by the suicide gene. I always got one or two die after pipping. I dont think you can get "pure" as the Jap banty is in its heritage. The Serama is a fairly new breed(its only been shown in the last 10 or so years) and the Jap is part of its make up. Also, they dont breed true.Trouble with heavy reading, reading, reading is, I cant remember what I read about rectifying it. Im sure it was dont turn the turner off till the day they are due and if in doubt give them an extra day.DSCF0114thl.jpg
