stag beetle breeding

[Defalt]

so I recently came into possession of some stag beetles, specifically, 3 males and 1 female.
I hope to be able to make them breed, but I have some questions to ask before attempting.
1.Is it ok if more than one females are present in the container?
2.Is it necessary to add decoration to encourage mating?
3.Is there a specific method to introduce the male to the female?
Lastly, please tell me any extra tips and tricks that I may not know, thanks a lot

What species ?

Pictures if possible?

 

[Defalt]

they're most likely some kind of lucanus, I believe

I actually already got them to mate, here is a picture I have. But I wonder, how long will I have to wait until I see eggs, and how long will it take for those eggs to hatch?

Any updates?

 

[Defalt]

yes actually, after digging around I managed to find a few eggs. I feel pretty relieved that something has come from all this trouble

the eggs vanished, is it possible that they have hatched? I do not see any larvae, but it is possible that they are simply too small to be seed with the naked eye or they are so small that they got lost
