Do i separate eggs from what looks like dead eggs

[Lisa24]

I have baby axolotl eggs that are 6 days old a lot are developing as I have seen them moving but I have some white thick round eggs left some fallen to the bottom of tank as you will see in pictures, do I remove the white ball ones now or when they all hatch? There’s not much information I can find in this subject so I thought best ask here, I have them in thier own tank without a parent.

Also I was planing on buying daphnia already live from a pet shop in a bag do I need to water them off so no salt or can I put the bag into the tank as it is?
