Well it hasn't really changed much since, here's a pic from today that i took (highlighted part is problem part)

Can damage that that happen from reversing. And will that go away after her next shed. I've stopped feeding them (mind you only the one female has been eating lately) to git them ready to brumate. I'm hopefully going to be moving as of December 1st, well gitting the keys to my own place then, moving wouldn't be till the following weekend. and then I'm going to figure out what I'm going to do about brumating them.
But ConcinnusMan if you think that it's not serious and that it's just from reversing then I won't be worried as much.
Thanks all
