Yeah it’s always the worst your first few hatch’s you’ll get less nervous as you go lockdown is the worst part but just leave them alone and it’ll be fine.
They take around 18 days to hatch.
Give them till day 22 they should start hatching in the next 2 days but if not don’t worry about it.
There is a possibility none will hatch but with them having veins it’s a low chance.
