Turtle Egg

A turtle egg is a block that hatches one or more baby turtles.

Breeding turtles
After two turtles are bred with seagrass, one of them travels back to its home beach, digs in the sand, and lays an egg block that contains 1–4 eggs after several seconds. The egg goes through three stages before hatching. Hatching occurs only when the egg is placed on regular sand. The egg cannot begin the hatching process if it is placed on red sand. The time until hatching varies (typically taking several day cycles), even for eggs laid on the same beach on the same day. The eggs can grow as well as hatch during day and night, but grow faster during the night.

Obtaining
Turtle eggs can be obtained in the inventory using tools with the Silk Touch enchantment. If broken without the enchantment, pushed by a piston, a gravity-affected block falls into its space, or the player falls onto it from a higher block, the egg breaks without dropping anything.

Usage
Turtle eggs can be placed similarly to normal solid blocks, and slowly hatch into turtles. Up to 4 turtle eggs can be placed onto 1 block. Turtle eggs only hatch if on sand (not red sand). They hatch significantly faster at nighttime.

If a player or large-enough mob, armor stand, falling block, or item falls or stands on an egg for a certain amount of time, the egg breaks. As long as the entity remains on the egg block, the eggs break one at a time until all eggs in the block are destroyed.

Most undead hostile mobs actively seek out and trample turtle eggs, breaking egg after egg on the block until all of them have been destroyed, unless  is. The range of detection is 23 blocks away.

A new egg placed near another egg that is about to hatch causes the new egg to hatch faster.
