Thanks very much for the replies. To clarify, she is 2 1/2 years old (same age as my girls that are 1400-1700g), because she went off food at 800g for a while. Eats great now though. I have a hatchling rack already that these 7 were in when they were smaller and I'm getting a second TGR FB70-5 this month. The couple has separated this morning and I'm setting up the old hatchling rack to temporarily move he male and smallest female to tubs there, while I await the new adult rack. I don't have an incubator yet because I had no need for it, but that will be built soon just in case.
I learned an important lesson about trusting tub dividers and underestimating the sex drive of a little male ball python!I'm going to make sure she is fed well in case the one lock produces eggs, but I assume she will likely just absorb the follicles.
