if she's close to the bottom of the rack, might want to move her to the top where the air temp should be higher. I have a female that I never breed, she gets a R I every year right around breeding season. this is the only snake I have that ever had a R I . I have about 100 ball pythons and if it was related to my snake room temps or humidity being off. you would think that one of my breeder females that is under stress from breeding would be the one getting a R I. I know a big breeder in my area that been in this hobby over 30 years and with more than a 1000 snakes. he told me that he also has a female that gets a R I every year. he tried different things to try to prevent it with no luck.
