When to worry?

O.K.,now I'm worried.My leuc. blackrat had layed one egg on 5-30 and nothing since.She still has eggs in her and does not seem to even try to deliver them.No "wringing" or "writhing".It's the 16th day past pre-lay shed.Has anyone ever had a female go this far past P.L.S.?
All other snakes that Iv'e bred usually drop around day 10-12 past P.L.S.
Should I try to manually manipulate the eggs?Or should I not worry so much and let nature take it's course and hope she drops soon?
The one egg she layed is very long and pointed on one end,but looks good overall.I will candle it in a few days.
Any replys would be greatly appreciated.

Hey Michael I am going through the same thing with a corn snake. She laid 1 egg May 27, 14 eggs on May 29 and she still has at least 5 eggs in her. I think I might get these out tomorrow morning if they arent out. I am getting worried too.....

Hey Michael, how is she doing?

All eggs are out.6 total.Here's the break down,1 egg layed on 5-29,3 eggs layed on 5-31,1 egg layed on 5-1,and 1 egg layed this A.M.5-3.Quite a span of activity.
3 eggs are of normal size and slightly off white(I think stained from the sphagnum) and 3 eggs are HUGE and very white.
After the 3 eggs where layed on 5-31,I was manually manipulating the remaining eggs down towards the ovaduct with my thumb.It seemed to work as I think she was exausted from trying to deliver.Each time I did this,she would drop one soon after.
I learned that sometime you have to step in and give mother nature a helping hand.My snake seemed to appreciate it too!Also after each egg dropped,I would hold the water bowl up to her and she would take a long drink and return to the laying box.What a trooper!
I am very releived that it all worked out good.I now have the laying box in with my quad. het female corn who is due to drop in a few days.She normally does not have a problem delivering eggs.
Now the 2 month wait to see my baby leusistic blacks.
Ron,how are you making out with that corn girl of yours?I wish you luck and keep us updated.
P.S.,I would post some pics,but I have used up my pic posting abilitys here.
Drop me your e.mail addy,and I will send one.

Well she is still pushing eggs out. She has laid 18 so far and I am going push the other 3 or 4 remaining eggs out now. She laid a lot of duds this year, 8 so far. She is getting up there in years so I think this will be her last year breeding. Poor girl usually throws 50 eggs a year like a pro but I think its getting to be too much on her. She will just be my friendly pet from here on out.
Congrats on getting those eggs out!
