In the past two weeks I have had 3 of my yearling corn snakes regurg. I had upped the food size a little, but I had seen them eat this size in the past. I usually try larger food items and then go back to the smaller size a few times to be sure they can handle it. Anyway, I had also lowered the heat a bit for these snakes also recently. Is it more likely for a snake to regurg with lower or higher temps. I still have them in the mid to upper 70's in the warm spot. Usually i keep them around 80 for the younger ones.
