I separated them at the behest of OWaL. I took her out and popped her and this is what is looks like. This is my third time popping her and in my opinion her cloaca area thing is way redder than the rest of my females. Is this cause for concern? I thought it was just because she was older than the rest of them. Any tips on my popping technique is appreciated as well. I want to correct any problems I have/may have with anything.

Thanks
