The 0 crystal hurry trick is available at the tail-end of a dino's hatching time in the Dino Den. The hurry cost will turn to 0 before hatch time ends, but depending on your initial numbers for hatch time and the hurry cost, when the 0 hurry cost appears will vary. You will be able to cut the hatch time short when the hatch times are longer and/or the hurry cost is low since the hurry cost does linearly decrease with the remaining hatch time. For example, when using Random Dino, it usually comes to 22 hour hatch time and 12 crystal hurry cost. Check around 1.5 to 2 hours left, and it should be 0 hurry cost.
