possible egg binding/laying difficulties in corn, please help

[ineedsoap16]

We paired our corn snakes together a few weeks back, we've been watching her and had a nest box in her enclosure anticipating the clutch (and watching her get chunky)
Nothing seemed to be happening, but when we checked today there was one egg on top but she's still just hanging out like everything is normal, except for how dramatic the bulge gets right above her tail, so we poked around and found a dried out little egg that was underneath everything and had to have been there a while and we didn't notice, but the fresher one was on top and is from sometime today, my husband (I'm not on as myself...) is very concerned and thinks something is wrong so he cut open both, the newer one he said is a slug and doesn't have any indication of viability, but that the smaller one looks to him like it had viable yolk in it (don't know how he came up with it because they looked like two different versions of the same thing to me) but anyway, does this sound like egg binding? and if so is there anything we can do to move her along? any help would be appreciated asap as he's very very distressed about her.
Thanks all
