Gold isn't much of an issue in this game, so normally you just find someone with a pet you want to hatch with, ask them for a hatch and they will help out. People in the hatching tent might however be hatching for self purposes and as such low on gold, so some of them might not be so willing. Just asking for help in skull island, where everyone congregates, typically results in someone stepping forward. Asking individuals in skull island, typically also results in willingness to hatch, as those standing around are typically bored and full up on gold with a need and/or desire to spend it down.
