On Saturday, one of my unsexed "male" cornsnakes started laying eggs. I never probed the snake, just checked the tail as it was in any case a bit small, in my opinion, for breeding so would have probed next year to make sure,
Long story short, this was a runaway snake that some poor guy found in his house and nearly had a heart attack, on a second glance he recognised it as a corn snake and brought it to me. I checked the tail, over all condition, made sure it does not have mites, checked the mouth etc and decided to take it in, it was in perfect condition.
I put with a normal male corn of the same size and checked that they would not fight. During the past week i had a spare cage that opened, and moved it to a new cage, on Saturday one of my customers were holding it and told me that something was wrong with the snake as there were big lumps in the belly, and within 20min, she laid the first egg. She continued the whole day and laid 10 beautifull healthy eggs. This posed a new problem, namely incubation. Weekends being my busiest times I did not have time to build an incubator, I found a 3l tub with ventilation holes around the top, so filled it half way with vermiculite, moistened it placed it in the cage for her to lay in, by this time only 2eggs has been laid. She was still busy laying when we had to leave, when we got back on Sunday, 10 eggs were laid in total, 6 of which was laid outside the laybox, in the cage, so by the time we got there the eggs were pretty dehydrated. Still without an incubator it was time for drastic measures to save the eggs, I placed the lid on the tub, added a thermometer, and left it floating in my Malawi tank. The tub is now kept constantly between 28.2 and 29C. So decided that it might not look the part but is probably the cheapest way to incubate.
The eggs has swelled and recovered fully by Sunday afternoon,
Wil keep you posted on the development. So if you unexpectedly get eggs and have a tropical fish tank, which runs on higher temps you could always incubate your eggs in there
