Can confirm. This probably works as intended, however, I do not make that decision. This very closely relates to MC-218528. Here are some steps to reproduce this issue for clarification reasons:
Steps to Reproduce:
- Place down a singular lit candle.
/setblock ~ ~ ~ minecraft:purple_candle[lit=true,candles=1]
- Obtain a purple candle and place it on the same block as the already lit candle.
→
Notice how the candle that you just placed is ignited.
Repro steps
Video attached. Also affects 21w10a.
With the block states that turtle eggs have it isn’t possible to fix this. Fix would require making different turtle eggs on the same block have different hatch states somehow.
Or, another option would be to not let players place turtle eggs on cracked turtle eggs.

I believe the easiest fix would be to just disallow placing turtle eggs on already hatched turtle eggs. This could be done by adding a new condition to check the HATCH value inside TurtleEggBlock#canBeReplaced(...):
... @Override public boolean canBeReplaced(BlockState $$0, BlockPlaceContext $$1) { if (!$$1.isSecondaryUseActive() && $$1.getItemInHand().is(this.asItem()) && $$0.getValue(EGGS) < 4 && $$0.getValue(HATCH) == 0) { return true; } return super.canBeReplaced($$0, $$1); } ...Can confirm in 1.19.3
