Seems that the Girl was too small for breeding...
We are very careful when we breed our girls, to insure that they are mature and healthy enough to handle both the gestation and laying process. We also make sure that they have good muscle tone (as best we can) and are not just carrying fat.
Not every corn snake lays double digits for a first time clutch. There is variation in the numbers, with an increase in the total number rising each year (typically, but not always.) There is also a possibility that she dropped a slug or during the week before she laid that I might have missed when cleaning out her cage and that would account for the low number of eggs.
The other thing to take into consideration is the fact that these eggs are fairly large - much bigger than I expected truth be told. Than again, maybe the male has a low sperm count and the unfertilized eggs were reabsorbed. Or she could even have another egg or two sitting up higher that she hasn't laid just yet - she'll be monitored over the next several days and still has her lay box just in case.
Maybe I'm reading an accusation in your post that you hadn't intended, but I found it extremely offensive that you automatically jumped to the conclusion that she was too small and inferred that we were irresponsible breeders.
I don't know if that is what you intended, but that's the way it came off.
The female above had absolutely no problems laying her clutch, all were dropped within about a 5 - 6 hour period AND she's looking fairly good if a bit skinnier that she was prior to laying. She also ate a small meal for us earlier tonight without any hesitation, and is far from being lethargic. In fact, she tried to bite me when I extracted her eggs from the lay box - I seriously doubt that she'd be that spirited if she'd been breed far too small or too young.
That said and done, I'm looking forward to seeing these eggs hatch, as both mom and dad are beautiful snakes with great feeding responses and easy going personalities. (except when they are hungry or annoyed because you're stealing eggs...)
