I have an LG 9200 with 7 "mutt" eggs due to hatch on Father's Day (June 21st). I'm hatching using the egg carton method and tipping the 'bator from side to side 3x a day using a box top that's about 6" tall. When I tilt the 'bator one way, it will hold temps fine and no adjustments are needed (stays stable at 101.5). However, when I tip it the other way, it will spike up to 102-103 and I have to make adjustments and pull the vent plugs out for a bit to get it to cool off.
Has anyone else experienced this? What could be causing it? So far, I have 7 fertile eggs, and I would sure like to have 7 chicks on day 21!
Thanks!
