my baby ball python has been acting really shy lately for almost two weeks. when i first got him he was always out and about or under his log where i could always get him. now he is in this tight cylinder type hiding place that has three holes in it for entering and exiting but i can't remove him he has to come out on his own. the only time he comes out is when it's feeding time. is this behavior normal and he just likes the hiding place or is he sick?
