From what I have read in the past I dont think there is harm in leaving them together but if you notice one of them "going bad' that is one you should separate but I am no expert 

I also believe that just before they hatch (within ten days) they will soften again and you will be able to pull them apart. 

Dental floss? I always just pull them apart. Of course I'm talking about rough and tough corn snake eggs. I know nothing of your silly duck-faced snake eggs.

I think leaving them how they are is fine, I've seen big breeders do that. Of course I haven't bred balls, but I think it's sound advice. :)

what Steadfast said.......

I think you guys are missing my main concern, will the pressure from the top eggs hurt the ones on the bottom?

Nope, not at all. : )

^ No of course not. Is this your first time breeding snakes or something?

Lol, well my concern was because of the light diffuser, I've never used one and I was worried since the pressure would be on a thin grate rather than displaced on solid bedding.

i see. that's legit, but no... you're fine. they're fine rather.

Nope , I agree , no need to spereate . The hatchlings will find  a way out. If you try and seperate them now , you run the risk of busting eggs , that wiould be nooo good :*( Best of luck to you!!

fine, fine, fine!  I hatched a clutch that way with no issues at all. out of 12 eggs, there was on stillbirth, but it was on top of the pile.

Yeah I wasn't really worried about them not being able to get out, just the pressure of the top eggs being transferred onto the grate had me worried and I wondered if I should put them on substrate instead.  I've had piles like this before, but this is the first time I've used a grate instead of putting them in substrate.
