Stole an egg on Fjordur, was trying to position campfires and the such for awhile to get temp right. Then I remembered swamp island is hotter than the rest of locales. Flew there and in castle set up ten standing torches inside a wood building as well as a dimetrodon on each side of egg. Worked for me. Standing torches set up along one side of egg in a straight line. Hope this helps.
