If you got a Drake early or your running solo and don’t want to get all the materials for all those air conditioners I would recommend just taming a bunch of Dimetrodons (about 6-10) putting them in a room, and then putting the egg in with all of them. It should start incubating because Dims give a bunch of insulation. This should be much easier and you don’t need to go through all that mess just to get and run air conditioners. :)
