Passive

The formation of the hard shell being had completed, the egg is laid.

Actually i am trying to make this sentence with the help of perfect participle. sentences of this kid start with having.
so i wrote, Having been completed the formation of the hard shell ....the hen lays the egg. is this wrong?

AvidlearnerHaving been completed the formation of the hard shell ....the hen lays the egg.

I believe this is wrong. If I was restricted to using the present participle, I would say:

The formation of the hard shell having been completed, the leg is laid.

Those were wild guesses. You better wait and see what the teachers have to say abou

SurferThe formation of the hard shell being had completed, the egg is laid.

No. 'Being had completed' is not possible.

The formation of the hard shell having been completed, the egg is laid.

It's a pretty clunky construction.

"Having delivered the message, he left immediately." "Having finished his work, Harry was ready for play"
i want to make my sentence just as these sentences.

Having (been) completed the formations of hard shell, the hen lays the egg.

Yes, agree. What if the original statement was:

Having had the formation of the hard shell completed, the hen lays the egg.

Would my statement be accepted then?

Thank you.
