Ok, you have a serious problem. I am using the book "What’s Wrong With My Snake?" By John Rossi D.V.M and Roxanne Rossi as a reference. The hard stools you are referring to as rocks are called fecoliths or “fecal stones”. Overfed, under active snakes are prime candidates for constipation. Cooler air temps can cause the snake to “hug” its heat source, which causes the stool to cook. Low cage humidity makes the situation worse. This problem can result in surgery having to be performed to remove the dried “stones” if the problem is not corrected.
1 Make sure you are not overfeeding.
2 Make sure the snake gets some exercise, just by holding him and letting him move around will work.
3 Check you ambient air temps. Make sure the surrounding air is not to cool.
4 Check your humidity. Remove any drying substrates like corncob bedding or aspen. Consider using a humidifier.
5 Avoid using an untreated wood cage.
6 Try using warm water soaks 15 minutes per day for 3 to 4 days.
Hope that helps. Let me know if you need more help.
