I just ordered Cuckoo Maran eggs from 2 diff. people and the eggs all should arrive Friday evening or Sat. morning. I broke out my old Brower TH120 yesterday and got it all ready to go - lubed up, new light, cleaned - and it is running smoothly - preparing for 20 super dark eggs.... BUT.... after 2 days, one thermometer says "90" and the other says "95" . Neither are digital. One is stuck to the incubator wall and the other is kinda in the center. Is there supposed to be this amount of variance in the temp from center to wall? Anyone else have good or bad luck w/ the Brower TH210? I think it is the 2005 model. Thanks.
