Me and my buddy are on our server and his Nether Dragon hatched but my Water dragon will not hatch, is this a bug or is the water dragon just terrible at spawning time?

Can we not spawn 1 dragon at the same time, do we have to wait till one egg has hatched

Did you right click your egg to start the hatching? Missing that seems to be the most common reason for eggs not hatching.

Yes, we both tried spawning my egg multiple times and even tried turning it into a different dragon, it took 8 hours to spawn but it ended up spawning with a chunk loaded chunk while I was away

The egg hatching is advanced randomly in 1.19+

While I did not INTEND for eggs to take 8 hours to hatch.. it is certainly possible due to the nature of randomness.

I am however keeping a close eye on the hatching performance and will be tweaking as needed. I still am not sure if it's at a good point as of now.
