Nursery

"Monster eggs must incubate. Some will hatch quickly while others need a long time. The Nursery can only accommodate a single egg, but it will receive the tenderest of pampering."

Each island comes pre-equipped with its own nursery, which can be moved if so desired. There is only one hatching spot, and no way to get more places. Either eggs must wait in the breeding structure until the incubating egg is ready, or the incubating egg can be sped with gems.

Eggs that are ready to hatch can be sold straight from the nursery (without placement XP), or placed on the island.
