Quick answer
Warm the egg in an incubator to hatch it. In the documented ranch loop, you first obtain that egg by bringing a complete fossil set to Dr. Ivy’s DNA Lab.

Have an egg before incubation
Fossil collection and Dr. Ivy’s conversion come before the incubator. A missing fossil set is a collection problem, not evidence of a broken hatch timer.
Start the warming step
Use the egg and incubator interaction shown in your game. The developer confirms warming in an incubator but does not name the placement button or publish a hatch duration.
After hatching
The care task starts with belly fullness: keep the dinosaur above half full so it continues growing. Exact food items and feeding inputs require a separate current interface check.
