Standing torches and campfires will raise the temperature if it's too cold for the egg. Place a bunch Dow. And light them as needed, but keep an eye on the egg. The weather temperature and change and make it too hot or cold again. If you're able to craft ACs, usually 3-5 are good for smaller Dino's, but things like quetz and giga can need upwards 10-14 depending on your areanon the map and if you're hatching inside a building or outside. lternately there may be a kind tribe on your server(if you're playing on official) that may let you use their hatch house to hatch the egg, but feeding and keeping the baby safe will still fall on your shoulders, so be ready for several hours if hand feeding(putting food in the babies inventory till it hits 10% maturation and turns juvinile and able to eat from a trough) and then a few days of making sure you have enough froughs full of food, constantly, so the baby doesn't starve.
