It never ends... She is full again! On to her 6th clutch since February...

I really hope this is her last. My fault completely... I made a nest out of his tank hoping she would take to laying in it, but she hated it. Ended up going to my aunts and having he lay them in the back yard. Last time there were ants found in the nest the next day. She has treated her yard, but not sure it the ants are gone. The nest was a last resort, but I also need to separate this odd couple... So frustrated. Mostly with myself... Going to give her some time in the nest tank and will check on my aunts backyard in the mean time to see if it is safe for her to walk around and dig there. Not going to expose her to those evil little... Anyway, this situation has been unusual from the start. Anyone know of RES turtles producing more than the average 3-5 clutches a season? I had noticed that the last one wasn't small like the first couple. So if she has less this time, could I assume she is finishing her cycle? Also, the clutches has been about 2 or 3 weeks apart and symptoms would start a few days before she was able to lay them.
Clutches so far:
1st - 9 (3 were pearl size, 3 were smallish, and 3 were average egg size) (all fertile)
2nd - 6 (1 was smaller than the others) (half fertile)
3rd - 7 (all the same except 2 were longer than the others) (all infertile)
4th - 8 (all the same except 3 were longer than the others) (all fertile)
5th - 9 (all the same size) (all fertile)
6th - Will find out soon...

Any advice would be appreciated.
