Mona, I have seen this. Not just this year, but last year as well. I don't know what makes them do that. Maybe the seeds grow faster than the pod
If I know they aren't ready I just leave them alone. Sometimes the seeds will go on and ripen with time (if nothing gets in and eats the seeds or moisture rots them) if the crack isn't too big. Other times that chamber will shrivel up and the seeds will dry up with it, but the other chambers will keep growing and the seeds will mature and ripen. I would just leave them alone and see what happens. If you take them off the seeds may not be any good and if you leave them on the seeds may not make it, but given a choice they have a better chance on the scape IMHO.
But with 2000 pods Mona, you would be better off losing a few
If you have an average of 5 seeds per pod (remember some may have 10 or 15 and some may have only 1) THAT'S 10,000 SEEDS. STOP MONA STOP, you have enough
Take a break and give yourself some R & R before it's time to start harvesting all those pods and then planting them. It's too easy to get burned out if it becomes more work than fun.
Be proud of all you've done, but you DESERVE a break.
