Budgie eggs will hatch after a full 18 days. I had Budgie's many years ago. It was common for the eggs to hatch over 2 or 3 days. It wasn't a problem for a good breeding pair, they all got fed.

Agree had them myself

why can't they get out is the question

Could it be because of the thickness of the shell?

The thickness of the shell is determined by the amount of time it spends in the shell gland (uterus) and the rate of calcium deposition during shell formation. If the egg spends a short period in the shell gland, the thickness will be less

Maybe the eggs need moisting

he thought the hen sitting to tight and heat is drying the membrane out once exposed to the air might be the problem so next question is how often would you spray them as hatchings might be 5/6 days from first to last apart

Normally if a hen sits to tight the opposite happens. The hen will sweat, causing moisture. This is what happens with pigeons, in some cases the egg can stick to the hen and actually be carried out of the nest when the hen leaves.
As for spaying it should not be needed more than a couple of times.
