Hi all. Tom Keogan was nice enough to answer my questionst. I thought I would share the info here so maybe he does not have to repeat his effort. She would appear to be on the edge. Tom waits till the snake is 5'ish and 3 years old. However, he went on to say, that there was no harm giving my gal a try as Rings lay small eggs and therefore egg impactation was likely not an issue. Many thanks Tom!
