Nice snakes, Lora.
I have five babies from 2003 and I raised three before to adults. I may have a couple tips you can use.
The '03 babies are doing great. Four of them shed last couple days and ate two or three pinks each, live. When you feed live, sometimes they won't take f/t later. They eat best right after the shed. I would try to feed them again after about a week, or so. They can take a fairly large amt. of food in a meal. They don't feed too well after a couple feedings, until after next shed.
I had 1.2 before and the females got larger than the male. I don't know if that is standard, or not, but it doesn't necessarily mean a difference in age.
They seem pretty tolerant of dry conditions. My humidity is around 30% all winter, and closer to 50% in summer. They have never had any trouble shedding, or needed any extra humidity. I think they are intermediate bt. racers and ratsnakes myself.
They are pretty cool tolerant. I keep mine bt. 70 and 80*F. most of the year, with no extra heat, except rarely an overhead lamp. They never regurge. Adults can brumate for two or three months with no problems at cold temps, like around 55*F., or less. Oh, and they do better when kept alone, according to my observations.
Good luck...TC.
